I loved this show very much.
It has quite some feel from the original series and it seems to shy away from wokeness that plagued Discovery in later seasons (season 1 was awesome!!) ...that is; unless nbr 1 turns out to be ....u know..
merc has a point imho; about the storyline...which is somewhat lacking...but as for the age-questions I feel you are WAY off. I mean; if Scotty returns in Strange New Worlds as a 80yr old dude, then something is wrong. But Pike has "the right age" for the series and to "put him off" only because he's "trying to hard considering the actors age" seems a bit random to me and perhaps points to you not liking the actor as much.
As for Scotty: Simon Pegg or Paul McGillion (if they can due to "age-constrictions") - or someone completely unknown would also be fine by me...as long as he would do a good job 
REALLY looking fwd to next season!
