Automatic organization is leaving the problem to someone else. Again, you want control. You want to be sure that it's done your way because you are the one who will be using the photos and you want to be sure they're the right ones.

I would probably approach the problem as follows:

Connect a fresh clean disk and create a folder 'Archive' or some such name. Copy ALL the photos into that folder. Then go through the process of identifying duplicates and selecting the one you want to keep. Copy them to a new folder structure and try to organize them in that structure. That way if you screw up the duplicate cleaning you still have your old photos where they were originally. When you've got your photos organized to your satisfaction, delete the old copies of the photos and copy the new folder structure to your primary location. Then save the scratch disk as part of your backups.

This is a focus-stacked image of a cicada. Anyone living in the South or Midwest should be familiar with their emergence now.

There are many species of cicadas, but they all fall into two categories: annual and periodical. Annuals, as the name suggests, are present every year — and the sounds they make are generally what you might associate with the noises you’d hear on a typical summer night. They have green bodies and black eyes and are most active during the evening and nighttime hours.

Periodical cicadas, like this one, have life cycles of either 13 or 17 years, emerging after underground development in large groups called broods. Instead of green bodies and black eyes, periodical cicadas have red eyes and can look especially striking immediately after molting.
