Maybe it is just a Florida thing but they use sunlight resistant thermostat cable around here.
I assumed it all was. A am not sure about the "wet" listing but since it doesn't have paper packing I am not sure why it wouldn't be. PVC is water tolerant.
The real issue I have heard about is "riser" and "plenum" ratings when that is appropriate.
You might have trouble if you needed plenum, wet and sunlight in one cable.
