Of the schools I mentioned in post #18 as possibly having the stated major, or close,
the following graduated the fewest physics majors (not applied physics since AIP didn’t break out in most cases) in 2016:
Lafayette- 7, Lehigh-9, Stevens- 10.

Few majors may result in limitations in # courses , and sections of courses, available in the upperclass years. But maybe that is mitigated if the undergrads take graduate courses.
The only one I see they broke out for applied physics specifically was Columbia, which had 8 graduates. Cornell apparently didn’t list theirs, but they have a big (relatively speaking) engineering physics program.
Re # 19 the cited interdisciplinary program would be relevant only if OP winds up wanting to pursue that particular subarea. One of the other schools I mentioned also had some kind of limited arrangement like that, it might have been Penn State. I don’t remember what particular area theirs was in.
