I know that clover is good at fixing atmospheric (gaseous) nitrogen and turning it into a more solid form that plants can use (much like nitrogen fertilizers), but I am not smart enough to know if it is particularly drought-resistant
Buffalo and Blue Gramma grasses are definitely more drought resistant than clover. They don’t grow very tall either, so you can stop mowing toward the end of the season, let them go to seed, and that will naturally fill in any gaps that might have formed due to drought, damage, etc.

It lives on far less water than grass in my experience.
Depends on the species of grass
Hard Fescue & Sheep fescue have it beat.
Tall fescue is about equal.
Blue grass, fine fescues, and perennial ryegrass require more water.
