That is a nice cage, I like the connected-by-door setup.
I think womas are a great choice. Even Children's pythons if you like the smaller stuff.
Do you like boas? Sized-to-fit boas include Hog Island boas, T-positive Central American boas.
If the room stays relatively cool, then black milksnakes are awesome animals. One of those snakes that you do not appreciate until you hold one for the first time.
