old and new are open, plugged in, and stating that info is migrating. But it’s been over 24 hours with no change. Is anything happening? How to double-check progress?

Force the new Mac to shut down and determine if the migration was successful.
Refer to How to move your content to a new Mac - Apple Support.
It's been my experience that when Migration Assistant gets stuck, it's often in "Other files and folders" or "Computer & Network Settings" so if restarting the Mac results in an incomplete migration you might want to try again and de-select those choices.
Or, the migration might be perfectly fine. You won't know until you restart the Mac, and 24 hours is long enough.
