Is FWC a significant advantage vs RWC? Seems to me it is...I remember
seeing the Chesapeake being sucked into my engine at low tide on the
Elk River. Although this would happen to a heat exchanger in a FWC
engine, the long term damage of corrosion, etc. seems much less.

Is it worth making a decision regarding 2 comparable boats if 1 is FWC
vs RWC?

Yes. Generally speaking. Also pay attention to everything about the
boat. Look for signs of neglect or shoddy maintenance. If everything
looks ship shape, chances are the running gear is well taken care of also.
