Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

I wouldn't use Arch on a Server. Everything you install will probably be in a docker container anyway, so fast updates for system packages isn't important compared to stability. Good choices would be Debian or Fedora Server. I personally use Fedora but the reason is just that I use Fedora on Desktop too, so I know they have really good defaults (They're really fast in adopting new stuff like Wayland, Pipewire, BTRFS with encryption and so on) and it's nice that Cockpit us preinstalled, so I can do a lot of stuff using a WebUI. Debian is probably more stable tho, with Fedora there is a chance that something could break (even though it's still pretty small) but Devian really just works always. The downside is of course very outdated packages but, as I said, on a Server that doesn't matter because Docker containers update independetly from the system.
