What's the best pricing model for a 6+ player multiplayer game with 2k wishlists?

I'm developing a multiplayer social deduction game that requires at least 6 players per match. My Steam page has about 2k wishlists so far. I'm torn between F2P with cosmetics or a base price ($10-15) with possible friend bundles. What pricing approach would you recommend to maintain a healthy player count? What's worked well for similar multiplayer games that need a minimum number of players?
