I'm afraid it will be no lounge in your case. Indeed, the only PP lounge is in ORY1 and is called Premium Traveller lounge. But you won't be able to go there with a BP for a flight from ORY3.
AF lounge in ORY2 is not an option as you said (AF doesn't accept paid access for TO pax). Same for AF ORY3 lounge and in any case, this lounge is non-Schengen.
