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.

Honestly Ive had the inverse experience where the package I need is only in AUR and not debian repos, but at least we can agree that Flatpak and Snap are terrible
That would be new for me. AFAIK Debian doesn't have that many packages (compared to AUR or even nixpkgs (see https://repology.org/)).
Regarding Flatpak: What packages do you need for a server with Flatpak? Desktop makes sense for me, but I haven't yet had any use-case/package for server related software in Flatpak.
I switched from Debian to NixOS for servers, 3 years ago, as I think it's easier to maintain long-term (after being on Debian on servers for years). A new install (after EOL Debian support) often is a little bit more hassle and requires a longer downtime in my experience (apart from the lack of reproducibility and declarativeness and the sheer amount of software packaged and configured in nixpkgs).
