I like the idea of the window feed through. In case of a lightning storm,

should one ground the feed-through plate at the window to a ground rod just
below the window?

Hi Bob,

Only if you want the lightning to go there.

First thought - Maybe this would help protect the house.

Too many variables unmentioned to guarantee that.

Second though - Maybe it would be better to let the coax float with the
tower, to avoid burning out the coax.

Think of it as a fuse. Do you want it to blow open, or continue
feeding a bajillion amps into the ground nearby? (Again, neither of
these is guaranteed to occur - too much left unsaid.) This could
elevate the local ground potential and if you take too long a stride
you could feel half that potential between your legs (does that
motivate you?). This is implicit to the next thought:

Third thought - With ground rods at both the tower and the entrance to the
house, could this create a noise inducing ground loop?

Connect the two (and beyond) per standard practices.

Is there any standard practice about this?

Consult your local library for the code. Such things vary from place
to place, but there are commonalities - no doubt many of them will be
discussed here shortly.
