You could install a version of ffmpeg-full locally, just for your user, with a different name. I do this for x265-mod-patman-git. It’s available as x265-mod and doesn’t conflict with anything.

Outside of the coreutils and builtins, I use git a lot for work, school, and otherwise. I prefer the simplicity and speed over a graphical client.

btop is probably one of my favourites, really easy and nice way to visualize the system status.
