Here are the RubberMaid sections I'm looking in... Could someone please help me choose one? Some of these have the right volume, but are way too tall and have too little floorspace. What do you think is best for my girl?

How big is she?

You dont need very high, 6.5 inches is all. The length depends on the size of the snake. You can put a hatchling in a 6 quart, 12 quart for a 200 grams and a 32 quart for sub adult to adult.

I personally put my larger adults in a 41 quart.

Picky eaters will usually do better in smaller tub.

She's an adult; about 3 years I think and 3'10"

What about this?

It's 15.75x21.75x7.9, which is like 40 quarts, right?
Would this work?
