But one issue that I can’t seem to find addressed anywhere, likely because it is so obvious to everyone else(!), is what should happen with wires entering via a conduit (other than use of a bushing).

The smaller oblong knockouts in the corners of the box have NM clamps integral with the box - no additional clamp is needed. The integral clamp is a metal clip riveted to the box that the NM cable passes under when you shove it through the knockout. The round knockouts in the middle of the box sides require the separate clamp.
