Brake fluid is hygroscopic, which means it absorbs water. It can and will absorb water in the form of moisture in the air. This is why your brake fluid reservoir cap has a gasket. If you are regularly bleed the brake fluid from the system you should not have to worry about the wet boiling point.

I bleed my brakes at least twice a year, so I use Prestone DOT 4 brake fluid. $3 per bottle.

Because of the hygroscopic properties of brake fluid, it is also recommended that you only use brake fluid from a sealed bottle, and dispose of unused brake fluid after a week.

I switch back and forth between Motul RBF600 and ATE SuperBlue, as they are the easiest ones to get locally. I don't notice a difference between either of them on track. The only reason I even use the Motul is for the color, so I can tell when a full flush is complete. The ATE is about 1/2 the price of the Motul up here. If I could find the ATE Type 200 Amber up here, I would use it instead of the Motul RBF600, and just rotate between it and the Super Blue. Get whatever is easier/cheaper to find local, as long as the specs are decent.

This, especially if you are using your car on street only. Got some to do a brake flush and clutch flush this weekend.

^^ This. I use ATE Superblue/Type 200 purely for the ease of bleeding. The colour difference makes a whole heap of difference and takes the guess work out of bleeding.
