I tested an installation of Focal using the Ubuntu 20.04.3 installation media (and choosing to install restricted software) and while I didn't have nvidia hardware some packages were suggested for auto-removal - chromium-codecs-ffmpeg-extra, gstreamer1.0-vaapi, libgstreamer-plugins-bad1.0-0 and libva-wayland2. These were also in the autoremove list for the reporter.
