How should I host Handbrake?

I'm currently using Handbrake on a windows 11 installation of a desktop computer. I am planning on turning this desktop computer into a NAS and media server to replace my current raspberry pi 4 system. Handbrake works great on this computer, but I was wondering how I could use Handbrake on this system after I convert it into a media server.

Given that I wouldn't normally have a GUI to work with for Ubuntu Server, would it make more sense to install Handbrake in a ProxMox VE container, or should I use the docker version of Handbrake? Would there be a performance impact if I were to use the docker container?

The docker container has a web UI, while if I were to use ProxMox, I could have a full fledged OS to work with.
