moments
Is there any way to combine/split moments? Mine are a serious mess from photo scanning as well as strange groupings.

No. You can simulate events in Photos and split the "moments/events" that way using the albums instead:
There's a way to simulate events in Photos.
When the library was first migrated there was a folder created titled iPhoto Events and all migrated iPhoto Events are represented by an album in the folder.
When new photos are imported into the Photos library go to the Last Import smart album, select all the photos and use the File ➙ New Album menu option or use the key combination Command+N. Name it as desired. It will appear just above the iPhoto Events folder where you can drag it into the folder
When you click on the iPhoto Events folder you'll get a simulated iPhoto Events window.
