Between my phone and Google Photos I’ve got storage problems. I have somehow gained 3 GP accounts over the years, and all are about full. I want to buy storage, but it only makes sense to do it for one account. There are a lot of photos on my phone that show on all 3, but there are also numerous photos (from prior phones) that are only showing on one of the accounts.

What I’d like to do is combine them all to one account, and then also delete a lot of photos from my phones storage. What is the easiest way to do this? I assume after they are combined there is a way to clear duplicates?
