Some of the bridges do seem overly cavernous. The Galaxy one has a view screen that I'm guessing must be 4 or 5 meters tall. Whenever I'm on it I just have an awkward image of my captains shouting orders with a bull horn.
Well before the belfast and the oddy bridge I found the advanced escort cstore bridges pretty nice and somewhat to scale. All the others even the KDF ones were just far too large, I hope to see new bridges in game added like one for the Bellerophon, that would be so sick.
I've always felt that the vast majority of bridges, especially on the Federation side, are either too big, or too d**n big. Looking at Starfleet bridges through all of Star Trek movies and TV shows, none of them show them as being as big as a stadium like they do in STO. Even the bridges of Starfleet's most powerful vessels like a Galaxy or Sovereign class ship have bridge sizes similar to what's shown even in Kirk's timeframe with the Miranda, Constitution (incl. refit), and Excelsior bridges. In short, they're not meant to be monstrous caverns. It's a pain in the rear for the captain just having to yell down to the helmsman to engage warp even in a non-alert status.
