Having families on board was never going to end well.The Galaxy was the break in the mold because Picard talks about how he was uncomfortable with children on board (in Farpoint), with his previous command being the Stargazer, a Constellation class from the mold of the Constitution Refit, original Excelsior runs and the Ambassador class.
IIRC the Odyssey offloaded all her non-crew at DS9 prior to going into the wormhole and subsequently being destroyed.
The shift towards more tactical ships had started earlier, I think the Akira class were already supposed to have been in service in 2368, right around or after Wolf 359
The Excelsior class is an excellent platform that lasted a long time with upgrades and refits but sooner or later the limited volume was going to be a problem, hence the development of the Ambassador class and then the Galaxy class.
The Akira was a direct response to Wolf 359 along with a few other classes like the Steamrunner, they tried a few different designs with the Defiant being one of them, they were generally small to mid size ships that were quick and easy to build with more weapon mount points (launchers usually) and improved fields of fire in comparison to their size, their crew requirements were quite small as well.
If you need a real world comparison think of them as being pocket battleships that are agile, hard hitting and can be built quickly with the Defiant being one/two steps beyond even that, the Defiant is the equivalent of a Navy Destroyer or even a Frigate with front twin mounted rapid fire cannons that spit torpedoes, its a warship nothing more and nothing less.
In fact its probably the first true warship/escort that Starfleet ever built, the E comes close but it can do other things and is too big to mount such weapons, it would not be able to capitalise on them except against bigger and slower ships.
If it was me I would put some of the Defiant's front cannons into turrets and mount them along the sides of the E maybe even in recessed pods, give the enemy a face full of rapid fire torpedo broadside but it would chew up ammunition so bad.
The B, C and D were all built with the same exploration/diplomacy focus and the E was a serious switch in that regard, it was designed by Montgomery Scott and he was a product of an earlier time when nothing was taken for granted.
It shows in the design of the E.
