I second this, my old server was previously OMV and then Proxmox. But with my replacement server I went Arch after loving my Steam Deck experience. You’ll learn a lot and I feel like the complaints of it constantly breaking aren’t true if you put a little effort before running updates. I mostly use it headless for remote development (LazyVim) and running containers (moved to Podman from Docker), but I also use Niri for the DE when I do need to use a monitor, for example playing Dwarf Fortress.

I selfhost ByteStash and then save anything I use frequently and reference it when I need it.
