Yep, most of my linuxes are headless -- but I do have a VM which I pass a graphics card through to for games and ai stuff though -- works really well (as long as you don't reboot the VM, it has a hard time attaching to the gfx card the second time for some reason, not looked into it much)

sysutils/vm-bhyve makes it quite friendly.

I wouldn't use it for work, though, just personal. Work is all enterprisey kubernetes stuff.

Edit: there is a 'proxmox-like' for FreeBSD out [0] -- I did try it on a couple machines and couldn't get the network working, but consoles seemed to work.. Kinda.
