I knda doubt any single market is consistently best, the value shifts too much depending on the match up and where the books are slow to adjust. Ive actually had more luck going against the crowd on the exact 2 goal margin when the public piles onto a blowout.
Last time that happened to me it turned out I just needed to clear my app cache and everything loaded fine after. Maybe try that and see if it kicks back in for you.
Probably the most logical pick if you think about it, they're about as far removed from both camps as you can get geographically. Still feels a bit odd though given how recent that final was.
honestly i backed morocco as a underdog last round and it paid off but france feels different. watched them dismantle poland and its just constant pressure, dont see moocco handling that for a full match tbh
