I like Alpine Linux. You could also try OpenBSD if you want a Unix that just works without as much struggle. NetBSD and FreeBSD are also around and have Linux binary compatibility.

Define "advanced".

Otherwise, just go with Debian, or Linux Mint

Do you mean you want something like AUR but binary ? Fedora Silverblue can answers that question because their only packages are Flatpaks. MicroOs is similar.

I spent so much time compiling my own stuff, it was horrible at times, hours and hours. Now I'm using MX Linux and that's it. LFS is fun to learn a lot of things nonetheless.

Assuming your goal is to gain knowledge about operating systems

Try arch but without kde, gnome, xfce, lxqt... make your own DE, based on a WM of your choice. That way you'll gain lods of knowledge about how an OS interacts with the user and which applications do what.

After that, you would have to go for LFS or Tannenbaums Modern Operating Systems

LFS and Gentoo, you have to compile, sure... but Arch? You don't compile the kernel on vanilla Arch, if you mean packages, then just get the *-bin versions.

Edit: misunderstood your post. What's wrong with Arch and Arch-based distros?

Opensuse Tumbleweed

I have to shamelessly plug for Arch Linux here. I think Arch would be a great way to get into the more advanced side of Linux without quite delving into the complexities of LFS.
