Standard STF theory says that the head/tail wind does not matter for
cruise flight. Does wind influence best speed for final glide ?

It's two separate issues. *Speed to fly AND altitude required. *Speed to
fly is NOT dependent on HW/TW. *HW/TW will affect Altitude required.

HW/TW also effect speed to fly to achive best glide over the ground.
The rule of thumb is to add half the wind speed to the best glide
speed. I am also not sure it doesn't matter for cruise flight. If you
have a 50 knots head wind you will not make any progress unless you
fly very fast. From what I understand from cambridge manuals they do
not take the wind into account for speed to fly.

To get the MC setting for best glide distance into a head wind just
rotate the MC knob to the setting that gives the minimum required
altitude. Unless the wind is constant as you descend you will have
to keep adjusting the MC as the low point shifts.
