We often advise people to provide all the documents asked for, and then to have a "second folder" with you at the appointment to offer further corroborating information. Put yourself in the place of the "immigration people" looking at a wannabee French immigrant. What information would YOU want to know and have verified?
Bring confirmation of your AirBnB booking. That way you'll have it should they ask for it. Same goes for anything you can provide to "prove" your "artistic and cultural" status - flyers from shows, listings of publications, whatever might be relevant. It may come in handy - and if not it only adds a little extra weight to your sack or briefcase or whatever container you're using to bring in your documents.
