[Star Trek] After Kirk's visits, how come we never see or hear anything about the highly-improbable gangster, Roman, or parallel American/Russian culture planets?

You'd think that such planets would have huge sociological interest for the galaxy, and yet they seem to completely disappear from the historical records.

The records you're referring to really only focus on the 5 year mission for the first USS Enterprise.  The Enterprise (and largely the whole Constitution class) was and exploration ship, not a science ship, and thus it lacked the specialized crew and equipment needed for long-term study.  It's likely the Federation dispatched a more specialized ship and crew to study these sorts of planets.
