Proxmox is a great solution if you want to quickly spin up discreet VMs.
If you just want a server to run docker containers then I'd recommend a Debian lite server with Cockpit webUI. It just streamlines so much and avoids the layer of abstraction you will find using something like Proxmox. Proxmox just seems a better fit for a larger server environment where you have loads of RAM and CPU cores to delegate out to each VM or LXC.

That has been my experience.
