Which enclosure size would be better for any of the species in the Theraphosa genus: 20 gallon (30 inches x 12 inches x 12 inches) or 40 gallon (36 inches x 18 inches x 18 inches)?

That depends on the size of the spider. For an adult one I would use as large as you can afford. I would try 40 gallons. Looks great if you have real plants in there.

What's the size of the T? The size very much depends on the T size.

Basically, which tank size would be better for an adult female of any species in the Therapshosa genus?

Again, it depends on the T size. adult female T. blondi can be anything from 8" to 11".
My formula is square the diagonal leg span (DLS) of the T and then multiple that by 4. As long as the floor area is larger than that number, the T should be fine.

Assuming 8" DLS, the floor space should be at least 256 square inches, meaning the 20 gallon (360 square inches) is fine.
Assuming 11" DLS, the floor space should be at least 484 square inches, making the 20 gallon too small.

My stermi lady is in a Exo terra Habisphere, which is around 17 inches by 12 inches, & 12 inches deep. And as you can see she still has some growing to do.
