I am re-plumbing part of my pool filter system. Previously,
a 3/4-inch metal valve was threaded to 3/4-inch PVC piping.
The PVC piping has a PVC male adapter, which fits into the
female threads of the metal valve. I am replacing the PVC
male adapter but find it is a very tight fit. A lot of
torque would be necessary to get it into the previous depth.

I have a 1.25 inch metal valve connecting to a 1.25-inch PVC
male adapter with the same situation.

Do I just use teflon tape on the threads and then apply a
lot of torque until each PVC male adapter inserts at least
halfway into its metal valve?

Thank you in advance.

An alternative to teflon tape is also non-hardening thread sealant. It
helps act as a lube for pipe tightening. I used it to connect my 1.5" PVC
from my household pressure tank to metal valves controlling my in-house
supply. I got an extra couple of turns out of it using the sealant, which
cured a slow leak problem I had after my initial installation.

Another well regarded sealant is Teflon pipe dope. Very slick and non
hardening. HTH

Pipe dope is the best yes
