Oh, I agree. I just think having more age appropriate choices for other characters would have been nice too.

Spock and Uhura seem to be roughly the right ages for the time the show is set. But Kirk is too old (the actor hides it well, lucky bastard) and Scotty far too young.

And McCoy makes no sense if cast too young given the nature of his personality, relationship to Kirk, etc. So, like you, I would prefer to go older as opposed to too young, like they did with Scotty.

I think it’s the inconsistency that bugs me.
