Is there anything I might be missing? Should I get an appliance repair
tech in to measure the pressure drop across the compressor to see if
that really is the problem, or have I covered all the bases already and
proving that it's a lack of refrigerant is just a waste of money?

If you get a tech, don't back-seat drive and let him do all the tests he
wants to figure out the problem. If he's slowing down on the testing and
hasn't done your pressure drop thing, ask him to do it, if you still
want it done.
