The only reason I recall for the Intruder was that the pilot couldn't reach
the trim breakers in case of runaway trim.

There were systems failure emergency action procedures steps in the
Tomcat
(and Intruder for that matter) that required a back (or right)-seater to
perform. Both of those aircraft are crew-served weapons systems.

For the F-14 none that I recall, but it's been a long time. OTOH, the IFF
is back there and the post start BITS (which are a prerequisite for
flight)
are initiated from the back seat.

A-6 and F-14 were designed for crew integration to a greater degree than
the
F-4 (which you could fly solo). Needless to say none of the three gave
the
pilot any significant control of the radar.
