Let me get right down to the question: Is there such a thing as "medium-pull" brake levers?

I've been searching for a definitive answer as to which flat-bar levers work with what (specifically: TRP Spyke vs Spyre.) What I've come to understand so far is that long-pull levers have a radius of 42mm, as opposed to the 21mm radius of short-pull levers.

However, all of my modern bikes have the same SRAM/Avid levers - with a radius of 31.8mm:





Each of these bikes has a different kind of brake: one has regular V-brakes, another has mini V-brakes, and a third has mechanical disk brakes.

So, does this mean that these "in between" levers will work equally well with either road or MTB disk brakes? More specifically, does this mean that I'm free to choose between the Spyke (long reach) and the Spyre (short reach?)
