Back-button AF is super convenient for this, too. No need to worry about turning AF on and off, you just hold the button when you want it and let go when you don't. With enough configurable buttons, you can even have multiple AF modes instantly to hand - I do this on my D500, for example, so I can coach in on a sitting bird with group AF on Fn1, and then get tack-sharp eye focus with single-point mode on AF-ON, and not ever have to think about dinking around with control dials or menus while I'm shooting. Now that I think about it, that obviates my shutter focus priority setting anyway, since half-pressing the shutter only locks exposure. Oh, well...
