Other than the potential of excessive blow-by (unlikely but it does happen) there are only a few items you did not mention but may have already done:

Clean the vacuum nipple for the PCV system with a stiff wire or tiny drill bit. Often you will find it clogged but it also gives you chance the verify that it is in fact the brass nipple with built in restriction (it is hard, but not impossible to swap them).

Check for other vac leaks NOT a part of the PCV system. Enough or big enough ones can reduce the available vacuum so much the PCV system becomes ineffective. Unlikely but still possible.

Replace the oil cap seal.

FYI, that plastic oil cap on your car will dance pretty much no matter what. unless you add some weight to it to approximate the old style metal cap.

Stupid question, but is yours a turbo with a vacuum pump?
