However we have no idea quite how well off the OP is

Reasonably so, to be proposing staying in a hotel in Cambridge, hiring a
car and driving 100 miles a day in it.

Don't FCC have some complex restrictions on trains out
of KX if you happen to hold an off peak ticket?

Not really. If you have an off-peak day return ticket from Cambridge
there's a simple blackout period of 4.30pm to 7pm. To avoid whatever the
rail equivalent of "rat-running" is, FCC have a rather complex system of
rules for other journeys, but that's not relevant to the OP's requirements.

In any case the sensible ticket to buy is a weekly season, so all the
time/route restriction stuff is irrelevant.

For weekly seasons, the OP should note a photocard is required - easily
obtained from any rail station ticket office, but if you want one you
need to give them a passport sized photo first. You also need to give
them your name, or at least a name, to appear on the photocard.
