Lore written in the old Starship Tech manuals which I seriously need to reread sometime was that come TNG era Klingons while not known for it, were some of the finest engineers in the galaxies when it came to starship design. Very fast, agile and powerful deep space raiders that could punch well above their weight. Anything they built was designed to last, be easy to repair and very accommodating of future upgrades.
Cardassian ships had a similar simple, easy to repair and designed to last principle as Klingons but theirs were designed for squadron tactics and often nowhere near as powerful as any of their peers.
Federation ships were meant to be impressive feature wise but suffer heavily from over-engineering that bar a few ship types means they have to design a new ship whenever hey want to really want an upgrade.
Romulans were also similar to Federation ships in they tended to suffer from over-engineering and had a habit of having their bark a lot worse than their bite if you really challenged them with a similar class of vessel. They had tremendous power output and definitely packed some serious firepower along with strong shields, but they were also slow and very vulnerable once their shields were down.
Ferengi were basically raiders mixed in with a casino, can't remember what the fuck the lore was exactly but generally they bluffed a lot.
Breen were meant to be an unholy offspring of Klingon and Romulan ships iirc.
Dominion were a sort of wild card race in design. Having cheap expendable squadron ships like Cardassians, then also have Battleships similar to the Romulans and Federation.
Mind you this is fluff written close to two decades ago and when writers had a massive boner for Klingons
