I do agree that FT is the sensible place to post such a query. Even if regulars on FT might be quite bored with the compensation posts, this one is a fairly "original" one.
The OP asks for practical advice. The delayed flight was operated by A5 (Airliner of HOP) and my suggestion is to keep insisting with A5 (not FB).
But I doubt that they will go beyond their goodwill gesture of full refund and giving a free AF ticket CDG-PUF.
