There are a number of ones I'll echo that have already been mentioned, both ones I think are highly likely to win/get nominated at least (Tracy Letts, Tony Shalhoub, Amy Morton, Rob McClure, Kristine Nielsen) and ones that I agree are excellent rallying cries that might not get far enough (Keala Settle, John Bolton, Carrie Coon, Ryann Redmond).
But honestly? To me the nomination and/or victory I think will be most appreciated by me will be a Lighting Design nomination for PICNIC. Something about that production and the gorgeous way the lights and the set (also one I'd stump for, but I'm picking one and the set might have a bet shot) interacted... they were breathtaking to me. The Act II scene under the bright orange street lamp brought such an acute sense of place and time of day to me that it still takes me back just recalling it.
Words don't deserve that kind of malarkey. They're innocent, neutral, precise, standing for this, describing that, meaning the other, so if you look after them you can build bridges across incomprehension and chaos. But when they get their corners knocked off, they're no good anymore…I don't think writers are sacred, but words are. They deserve respect. If you get the right ones in the right order, you can nudge the world a little.
