If you want something that "just werks" to shitpost online and use some other programs, Arch based distributions are very good, and there are some that offer you a simple and easy graphical installation if you don't want to do it with the command line. There's Artix for non-systemd shit, Parabola if you want to go full-libre, or Manjaro for something as easy as Ubuntu.
Arch has its repositories, but there's also the AUR, which some people like and some don't, but it exists if you want to use it.
You could also try something like Linux Mint, which has versions based on either Ubuntu or Debian.
