I use NixOS, but it is not for learning how Linux works; realistically it’s for when you already know how Linux typically works, so you can understand when it breaks some of those norms.
If you want to learn how containers etc work, use straight-up Debian.
I really don’t recommend arch for a server. On a desktop absolutely but what I want for a server is to be able to let it sit for 6 months, then update it and not have everything break; arch works best with frequent update hygiene.
