What OS is best for a palworld server?

I want to setup a Palworld server for a friend of mine. Unfortunately SteamOS isn't available on their site. What OS can I use to setup such a server? I want to run it on a HP microserver N36L. Preferably I want to maintain it through a web GUI, so I won't have to connect a monitor all the time. Im mostly experienced with Debian like OSes, but im willing to try anything.

Thanks in advance!
