I'm not sure, but I would imagine if you go through the domestic side of the airport and use CLEAR, you could then take the skytrain to F (and your International departure may go out of E as well).
Irrelevant if precheck is open or not at F. I always get a card from the agent regardless of whether precheck is open or not. This allows me precheck privileges in the regular line. I have done this 100+ times for all of my domestic and international flights. Never an issue.
