Server Build! What OS?

Hey guys,

Looking to build my first home lab server and I had planned on adding a lot of the scripts provided by funkypenguin. I’ve been reading some and trying to figure out which way I’m going to go with this.

I do plan on using it to learn about docker setups etc, hoping to set up some services etc.
Also plan on running the Pirate stack and use it as Plex media server.

What OS should I be aiming for?
Unraid, does it work with docker-compose?
FreeNAS?
Proxmox?

Alot of these questions have been coming up, and I’d love to get some feedback. Thanks
