If you radically increase the height of the
saddle, does it typically make sense to move
the saddle a bit forward as well? This is my
intuition but I have been wrong before.

The usual "rule of thumb" is that the fore and aft position of the
saddle is set so that with the knee bent 90 degrees the ball of the
foot (just behind the large toe) is over the center line of the pedal
when the pedal is at its most forward position..

Be aware that this is largely just a good starting point and depending
on how you ride the position can be changed to suit your riding style.

The "rule of thumb" for saddle height is that sitting on the seat with
the hips level and the crank turned so that the pedal is at the lowest
point the heel should just rest on the pedal with the leg straight.
And again this is a starting point and the final height should be set
to fit the riding style.
