Kubuntu is most normie. Its just Ubuntu but with KDE instead of Gnome. KDE Neon has the latest KDE but the update process is a mess so I can't recommend it.
Personally I use EndeavourOS with KDE and find it very easy. Updates are literally just typing yay. But I understand that Arch based distros aren't for everyone.
I'm using kubuntu right now. Test it out fedora for about 3 hours before I ran into a bug and went back to the KUbuntu hard drive. Normie means it just works, or at the very least googling the answer leads to good solutions. Only ubuntu has that
I find that endeavor is pretty nice as someone who typically uses windows...I just can't wrap my head around not having a GUI for software installs. Like, I want to install jellyfish, but when I search for it, there were like 30 different ones to choose. Installed a package that I don't want, where do I go to find the exact name of the package and then uninstall?
It was enough to send me to kubuntu, which is what's on my laptop now. Basically only use the laptop for the web too, so likely no reason to change anything up.
OpenSUSE Tumbleweed, great KDE defaults - up to date - stable. Does things a bit differently than most distros but it's pretty easy to get used to.
That what I use, and it's perfect
openSUSE Tumbleweed. It's rolling and reliable.
Fedora KDE spin.
Fedora kde
Fedora kde spin, kubuntu (ubuntu but with kde), kde neon (kde's distro). I've never used neon or kubuntu as a daily driver (just when I was looking for a distro) although they are supposed to be quite good, but I use fedora gnome as a daily driver and fedora kde should be fairly similar. You can also use distrochooser to find a distro that suits.
I've been using this for a few months now. It's really good. A normie might want to look in to Slowroll though for extra stability. Is Slowroll even out yet?
It's available, but still experimental I think.
I highly recommend Kubuntu. I don't use any snaps though. And I always install the LTS version. Been using it for over a dozen years.
I think fedora kde is the one you should go with.
If you go with kubuntu you'll be using snaps by default (which can be removed entirely with some tweaking) and they aren't actually good (as with the recent steam issues)
I'm using Manjaro because SuSE Tubleweed didn't want to install that day. People like to hate on Manjaro but I honestly don't know why - the defaults are fine and I very rarely have issues despite using software from the AUR
KDE Neon is pretty nice, it's probably my favorite KDE-based distro.
You can also check out:
Debian 12 stable with KDE is smooth sailing
Rolling release: openSUSE Tumbleweed Semi-annual release: Fedora KDE Spin LTS: Kubuntu (3 years), Debian (5 years), AlmaLinux (10 years)
I personally think semi-annual is where it's at. You get packages that are mostly up-to-date (and with Flatpak user-facing software is up-to-date anyway), and you don't have to fear that something will break/be incompatible with every small update.
I'm running TW and it's great. If you don't want a rolling release, OpenSUSE created Slowroll, that is supposed to release major updates every one or two months, which would probably be my go to if I were to start over.
Slowroll is experimental and it's still a rolling release that tracks tumbleweed. It might be less maintenance, but not necessarily more stable in terms of bugs. I've seen some people report pretty major issues with it in the last couple months.
Leap is the version you want if stability is your priority. You can even get the tumbleweed nvidia driver if you have an Nvidia card and want the latest driver. The only os I've used that was more stable than leap was debian. But Leap is much more flexible than Debian.
Everyone is waiting for Slowroll I think.
Fedora Kinoite, specifically the version from universal-blue.org.
It comes with all codecs (and even baked in Nvidia-driver if you want!).
Why that and not the normal (mutable) Fedora Workstation KDE spin?
This. Or, nowadays secureblue Kinoite!
Its a hardened Variant of ublue kinoitr, but I tested it and especially using the "userns" variants, a lot works
"userns" means user namespaces, a technology used by browsers, flatpak and Podman/Docker/Toolbox/Distrobox to create Sandboxes, isolating processes. It is used by default on Fedora, so these variants are pretty much like regular Fedora.
Dont think a secure Distro is user-unfriendly. It works pretty normal, but is simply way more secure.
If you want to use Firefox or Torbrowser, install their binaries.

You're going to get a million answers, mostly people saying to use which distro they're currently using. In my experience, KDE works just fine on any distro that allows you to install it out of the box, so I would choose based on other attributes of the distro, such as:
For instance, I personally like Debian and apt, but I would not recommend base Debian right now, since KDE 6 is about to come out and Debian will take a loooong time to get it. I have not personally used Kubuntu, but if it gets rid of any the bloat canonical has been adding to Ubuntu lately, it sounds pretty good to me.
Kde neon isn't bad. If I'm remembering right, it's based on Ubuntu and made by the kde team
neon is amazing
KDE Neon
I've had an excellent experience with endeavor OS, which can install KDE as well as some other DEs from the installation options. It's based on arch
Kubuntu, KDE neon, Debian with KDE.
MX Linux with KDE?
If you have an AMD machine it even has a "advanced hardware system" iso for high end pcs
Probably the most normie would be KDE neon (Ubuntu) as it's made by the KDE community https://neon.kde.org/
Personally, I use EndeavourOS (Arch-based) with KDE and it worked out-of-the-box for me.
Fedora KDE spin. One of the easiest to use distros without all of the annoyances of Ubuntu (e.g. snaps).
TuxedoOS
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
