What else is there to do in closed guard?

3 month white belt checking in. Pretty much only do no Gi

What else is there to do in someone’s closed guard besides attempting to open it? Don’t get me wrong, I for sure need to continue working on getting out of someone’s closed guard. But are there other things to do that are viable? Is there some weird sub that can be pulled off? Any way to gain a more dominant position without requiring breaking the guard first? I’m just curious, because whenever I’m in someone’s closed guard I literally dunno what to do besides spam the techniques I’ve learned to get out of it. Just trying to expand my game and have more options if possible
