It's possible you've not heard of #boxyBSD
I was lucky to get a TIL moment when @stefano boosted it's existence into my feed.
However you should know about it, learn something about the user perspective from proxmox in the process, while working with a boxyBSD VM.
Here are some nice screencaps of the boxyBSD site so you can ask nicely for a VM and learn to play with one of the *BSD flavours from a distance.
I'm sure you can duckduckgo the address of boxyBSD when you analyze the screencaps, right?
