This is a YMMV situation.
As you indicated later, the domestic flight will leave out of a different terminal, so you would typically not have access to the area of the airport which contains the F lounge.
There are reports of some passengers being able to access the F lounge (escort who meets your incoming flight agreeing to take you to the F lounge) but the one time I tried it, I was not successful.
Depending on your layover time, the domestic lounge is not bad...but no alcohol...and the real bummer...no shower.
