Fuck, my wife got a notice that she would have to increase her iCloud storage so last week began the process of ordering a backup of all her pictures so I could get them off iCloud and organized on some drives at home. We got 12 zips of the pictures along with csv's and some metadata, and I literally just finished iterating on the script to sort them into year-based folders and convert all the HEIC shit into JPG. It's running literally right now.

Guess I should've searched harder!
