Have to also add to the voices recommending Debian stable. I’ve used it now for ten straight years after I stopped distro-hopping for my servers and desktop, and I cannot imagine using another distro. It’s incredibly stable, but the best part of Debian is the absolutely expansive repositories that even the Arch User Repository can’t beat. Very rarely do I ever need to use Flatpak (ugh) for packages, or look to add in new external repositories.
