OpenSUSE, Fedora, maybe Ubuntu. I'd avoid immutable style distros like bazzite. They make things easier at the beginning but have other downsides where "normal" solutions need additional steps.

Generally you should be considering which desktop environment(DE) you want to use as well, cause it's the main thing you'll be looking at.

Mint is a good beginner, no fuss distro that runs the Cinnamon DE by default. It's also based on Ubuntu, built on top of the normal version of Ubuntu.

Ubuntu has several different options for DEs distributed as 'flavors' - Ubuntu itself comes with GNOME, but there's also Kubuntu which has KDE, and multiple other options available.

If you've got the time and a free USB drive, I'd recommend making bootable media for a few options to try them out - both Mint and Ubuntu(as well as many other different distros) have live environments to play around in when you go to install them, and it's worth trying out a few different DEs to see which one you like.

Here are my recommendations from last time I saw this question asked: https://lemmy.blahaj.zone/comment/17912220

Whatever beginner friendly distro you choose, I suggest you use it as if you were a grandma, especially if you have experience in troubleshooting Windows. It's natural to try to find the solution to a problem by doing a Google search, but first of all Linux changes quickly, so solutions that are older than 2 years may be outdated, over 5 years they likely are, and they may apply to different distros than yours, so be careful. Always check your DE's settings app first, those have gotten really good in the last few years.
Don't be afraid to ask in chatrooms if your distro has any, the myth of the rude Linux community is just that, a myth.

Mint, cinnamon.

Seems like Mint is the consensus and I don't disagree. Just some things to consider when choosing:

1. Desktop Environment/Window Manager (DE/WM) this is the software responsible for displaying your desktop and managing the opening and closing of graphical windows. Window managers are very bare-bones and might offer an experience significantly different than Windows. (See tiling WMs). Desktop environments do the same and more, and are often bundled with launchers and useful default programs like terminals and editors.

2. Package manager. Package managers are responsible for managing your installed software. There are a variety of options, and distros typically will choose one as their default. Pacman for Arch, Aptitude for Debian, RPM for RedHat, and others. These are mostly interchangeable for the end user, but each has slightly different commands and frontends. So just be aware there will be a bit of an extra learning curve moving from a distro that uses one to a distro that uses another.

3. Release cycle. Different distros offer different styles of releasing updates. Ubuntu and Debian periodically release updates in a cycle with major and minor releases. Some releases are marked for long term support and others marked as short term. Upgrading releases has been hit or miss for me, so I prefer rolling release distros. These distros don't distinguish major releases and simply upgrade in place. Each has it's own advantages, just be mindful of how often you will have to upgrade.

The thing about Linux is the back and front are separated, and you can customize the ux like crazy. So as you try stuff, pay more attention to package manager, how easy things are in terminal, compatibility, etc.

Try some shit.

Arch Linux

Yeah I said it. I never used Mint or Ubuntu, I jumped straight into Arch and then Gentoo and it’s completely possible

If you stick to beginner friendly distros, you’ll never really learn Linux because they don’t challenge you. Just keep Windows on another drive as a reliable backup OS until you figure things out in Linux

Pick any of the more popular ones at random; it really doesn't matter that much.

Ubuntu

Gentoo

If you're not looking to do much you might be better off with one of the immutable variants (silver blue, aurora, bazzite). The upside is things are not supposed to break too much. The downside is if it breaks almost any existing instructions on the internet prior to maybe 2022 will fuck the system up more. Tbh Linux changes so fast that's true for most variants, but you can reach back to maybe 2018 before you start to hit system-breaking legacy instructions.

Mint isn't a good choice, but if you want a generally straightforward system that looks like Mac (gnome) or windows (KDE) then fedora is a good choice.

None of these options will be as secure by default as a Mac or windows machine -- you will have to do a lot of learning and be generally technically inclined to get there. The immutable OSs will give you a small leg up there, just because you're running less random shit from the internet as admin/root, but the Linux community hates Intel and Microsoft so much it's taken a lonnnngggg time to adopt standard security techniques, mostly resting on their laurels from decades past. Will you get viruses? Probably not. But just because nobody broke in doesn't mean leaving your door unlocked is secure.
