The short answer seems to be no. Newer planes are much more efficient than older ones, but the most efficient aircraft and flight segment per passenger-distance are the A320 Neo and 737 Max making ~1000 mile flights.

Fuel burn is probably not the main reason airlines use the routing that they do.

I'd guess that staffing and gate time are big cost drivers. A lot of those "how Southwest succeeded" articles from back in the day cited very fast gate turnarounds as being a key thing— get the people off, get the other people on, get back in the air.
