Windows to Mac workflow

I have a Windows laptop now with Luminar Neo, and an iPad. My current workflow is to create folders with my Luminar catalog where I process my out-of-camera images. Then I export the processed images to a “saved photos” folder. I use iTunes to sync all of my “saved photos” to my iPad (I don’t use iCloud Photos), I like the photos on my iPad so I can view them offline. Note that all of the pictures in “saved photos” are in folders that are categorized by event, location, etc. because Windows photo doesn’t have albums like Apple Photos does.

I need a faster laptop and am thinking of a MacBook Air. I’d probably like to come out of the stone ages and start using iCloud Photos (I understand that it is possible to download photos to an iPad for offline use, and the photos are synced across devices).

How does Luminar storage and workflow work on a Mac? Do you keep your out-of-camera images and catalog out of Apple Photos, and then export them to an Apple Photos folder? How do I manage the movement of thousands of photos in 30 folders from Windows to a Mac?
