Photos Mac won't "Import All New Photos" problems with iPhone connected by USB and Flash Cards
My iCloud storage filled up again a few weeks ago, so I need to delete about 500 videos and photos off of my iPhone, but want to be sure they are first backed up first to Photos Mac. Because Photos Mac rarely offers to "Delete photos after importing", I need to manually free up space.
When I plug my iPhone 13 into my iMac, Photos launches automatically (unlike my camera's SD cards), but when I select "Import All New Photos", it refuses to import most, esp. videos and screenshots. I can try redoing import by selecting one at a time, but very tedious — before deleting pics off my phone, I have to open up each and every photo in Photos Mac to compare creation date and time — plus some pics never, ever import. I see lots of videos from 6 months ago that never imported. Photos also never offers to import images off of my camera's SD card, so I've been forced to drag and drop them onto desktop or "Air Drop" them instead.
Apple Support said that Air Dropping might mess up Photos' importing memory, esp. with SD cards and sometimes with iPhone 13. Maybe because it saw pics imported another method? They also said "iCloud storage Full" could confuse Photos, but I freed up ~10 GB last night and am still having issues with importing today.
Air dropping the biggest videos would be easiest, but if that is the cause of my problems, then I don't want to make bad situation worse. And I can't download directly from iCloud to my iMac, because that messes up my pics' creation dates and times. Anyone else had problems with Photos refusing to "Import All New Photos?" and solved it?
TIA!

iPhone syncs photos to iCloud account, but iMac does not because Photos Mac library is too big.
