If actually flying AA, being able to call the EXP desk is a huge benefit. Paid international first class tickets won't get you through to someone who has a clue how to do their job.

If you care about fancy lounges, several flights have J as their highest class of service (like most intra-asia or intra-europe flights). OWE allows access to the F lounge if flying one of those (on a OW carrier of course) while your ticket will only get you into the J lounge.

Honestly the rest of it is probably useless to someone who flies paid F. SWUs are only valuable if you can find upgrade space at booking (possible, but good luck) or are willing to waitlist and either risk flying the lower class of service (I'm guessing that that's not the case here) or willing to cancel the trip if they don't clear (I'm willing to do this, but apparently most people think this is crazy)
