For TOS, a company called Franz Josef Designs produced several licensed products which had some of this info. They are long out of print, though, as they were produced in the 1960's while TOS was still a prime time series on NBC. These were heavily used by the designers of Star Fleet Battles.

The "Star Fleet Technical Manual" had views of several Federation ships - top, side & front, IIRC. This included the Constitution-class Heavy Cruiser of course, plus the Scout, Destroyer & Tug (with various cargo modules). There was a page for the Dreadnought as well, but IIRC it was presented with fewer drawings as something for the "future" - not yet deployed by Star Fleet. No non-Federation ships were included.

FJD also produced a set of plans for the Constition class. This showed details of every deck.

The original SFB Designers Notes made references to such deck plans for the Klingon Battlecruiser and Romulan Warbird (as sen on TOS), which the SFB designer says were used in determining what those ships carried. I never saw these myself (I owned the first two).

I don't know of any web site with this stuff posted - probably would be of questionable legality anyway. You might try through some service that finds out of print books.
