Well, I've opinned on this subject a few times, Here's a reasonable explanation I've come up with ( and of course litteral IRL reason of.. Money for makeup on a TV budget)
Starfleet is a mostly human show because.. "Drumroll" Humans are the most adventurus and risk taking speices in the Federation.. So in my mind, humans join starfleet by the boat load, as compared to say andorians or vulcans etc. and so make up the bulk of federation crew..
May also be that alot of the other speices just dont have a reason to serve in starfleet.. Maybe a pacifist spieces, or they concentrate more at home, or they join the local Home Fleet, or there incapbable of operating comfortably in a Earth type environment, without an environmental suit of some kind. example, Homeworld gravity is low so hurts to serve in 1G, or gravity is high and has other detremental effects, or aquatic or gas cloud, or to small, to big for the decks.. whole slew of reasons.
Now, we see mainly human ships, but there are ships that cater to a single species, say the vulcans and the intrepid, or a water ship for aquatics, or a larger ships for a 3 meter tall speices.. etc. Weve only seen a handful of ships..
