I personally would recommend Fedora. It's not rolling release like Arch so packages might be a bit behind, but with Red Hat using Fedora as their staging distro it's usually not very far behind and occasionally even ahead. And you don't have to worry about updates breaking everything. It's also one of the big distros so it's well supported

Any of them that isn't some opinionated special feature distro besides Ubuntu.

Just pick one. Arch, Debian, CentOS, Fedora, any niche little distro, and if you're opinionated about something theres devuan, alpine, void, NixOS.

About the only ones I don't recommend anymore are Ubuntu and Manjaro.

There's no easy answer, the Linux Desktop world is more fractured today than ever. I use and like Ubuntu, Debian 11 has had driver issues for me. I don't like RPM distros. For Ubuntu, I had to uninstall snapd and pin it to never be installed. For Firefox, I downloaded it, unpacked it and use its Help menu to update it. I don't use Chromium because Ubuntu only ships it as a snap now, I use Chrome.

PopOS, SuSE maybe

EndeavourOS is the easiest way to use Arch imo, its a pretty painless installation and gives you a working desktop environment out of the box & seems to be pretty good at detecting hardware and installing drivers too.

OpenSuse tumbleweed.....rolling release that has snapshots. Up to date software, the open build system, yast

fedora

debian, maybe debian Sid
