Yeah I happened to notice that the F seats on the 763 today (straight-forward facing seats in the center section) looked like they had larger side tables and extra room down on the inside of the seat. But I still prefer the ones against the window for privacy and the “foyer” where I can keep my bag during the flight. But if none were available I’d probably take an F seat over the angled ones even at the window as those don’t have any extra space (but maybe larger footwells?)
I’m usually on a 763 and I’d say 3 or 5 A/L are my top choices.
