OMG. Simplest solution ever:

Restart your MacBook.

Software Update popped right up with the firmware update. Cheers!

I'm having the same issue. Just set up my Studio Display yesterday and, even running Software Update via a Terminal command, no updates are listed (I've been on macOS 12.4 since it came out).
