Ultimately up to you, but I’d go with no GUI and just use ssh (and sftp if you need to do file transfers).

When I was using Docker, it was headless because the GUI just ate up space and resources I didn’t need. All your interaction will be in the shell anyway, launching your compose.yml files.

But, if dealing with a headless machine sounds like more trouble than you want to try, install the DE if your choice and breathe easy because it’ll still work perfectly fine.
