I'm not expert, but one thing I noticed in a lot of sci-fi designs is that people put big honking engines on the back but they rarely ever put any sort of manoeuvring jets around the body of the ship. One thing to also consider is that if the ships don't have artificial gravity + dampeners, then up is going to be the nose of the ship because whenever the engines are on it will create gravity. So many ships would create gravity by for example accelerating at 1G.

And one other thing, I think it's a benefit to understand why ships have certain names. People just tend to transpose the WW1 naval designations into space without actually understanding that each ship had a specific role or purpose in the fleet and also that the names of various ship classes were born out of their purpose or role.

A destroyer for example is called a destroyer, because its full original name was "Torpedo Boat Destroyer" and it was meant to intercept smaller torpedo boats and protect the Battleships from their attacks. But in the British navy for example, an Invincible class Battlecruiser displaced some 20,000 tons whereas a Q-Class Destroyer displaced only 2,000. A BC had a length also of 567 ft whereas a Destroyer was 358 ft.

Anyway, the point is that knowing these sorts of details can help inject some element of realism or consistency into one's universe. So instead of creating a ship because something is cool, you create a ship because in the world you're creating there's a need for it. This ship exists, because this nation built it for this purpose. And if you do that, then the nation and the people of that world gain a little character and story.
