Merging Multiple Photo Folders

I had an iCloud snafu about 3 years ago and a senior advisor at Apple had me backup all my stuff a few times. So, I have the following under Pictures:

What is the best way to make sure all are merged into Photos Library*, deduping, and getting rid of the extra folders? There seems to be 5 folders where only one is needed.

(I’m assuming that Photos Library folder what Photos is putting stuff like the screenshot I just uploaded here.)

I have Gemini 2 and Photosweeper at my disposal.

I saw a couple threads but not exactly like this and I don’t want to do something stupid here.

Thanks in advance.
