Board Game Arena

I've got 7 Wonders and 6 Nimmt! on my list.

Any other suggestions for games on BGA that accommodate 7 players?

You might filter all games for those fitting for 7 players: https://boardgamearena.com/gamelist?players=7

You already know 7 Wonders Architects. Cosmos Empires is another light engine builder. If you are looking for interactive games you might try Bang, No thanks, Saboteur or Room 25. If you also like multiplayer solitary games, you could check Welcome to and Can't Stop Express, where all players play at the same time (so no downtime). Very nice communication games (guessing words) are Just One, Concept, Pingimus and Decrypto. If you are not familiar with this genre, try Just One first, because it's much fun with very simple rules!

Sabatuer for sure.

If you're not afraid of games a little bigger/longer, there's Heat now allowing up to 7 players.

Not on BGA, but Diplomacy is a 7-player game. When I was a teenager (a long time ago) I walked into a game store and asked for a game our family of 6 could play. Diplomacy is what they sold me. SO inappropriate. But I enjoyed playing it with my friends, even though it led to some of them not speaking to others for a while

For my weekly online gaming group of eight friends, we find Mojo, Solo, Papayoo, No Thanks, Incan Gold, and Welcome To, are very fun. But let's not forget Challengers, albeit with a robot if you play with seven. I would think Coup and Love Letter would work as well.
