Topic: Is there a "Steam Charts" for nintendo switch online games?

I was looking to buy mario party, splatoon and shredders revenge, but I'm mostly interested in playing online multiplayer. Is there a way to see if the online multiplayer is still active? Or is there anyone who has these games able to find online matches?

I don't really like the gatcha type games, but those that have cross play seem like the only switch games with constant online activity, other then mario kart and smash.

I'm not aware of a way to check but I can confirm Splatoon 3 is still extremely active online.
