What are the popular Rapid time control settings?

I'd like to start playing more Rapid time controls and I'm looking for the popular options so I dont have to wait too long for a game.

I see that 15 | 10 is offered here but for my purposes that's a bit long. Over at Lichess 10 | 0 is classed Rapid, but here that is  still in the Blitz time scale.

I did try creating a 10 | 10 seek here but it was not accepted after waiting a while.

So, other than 15 | 10 what Rapid time control should I search for to get a game without a long wait?

10 | 0 is blitz, so I think that 15 | 10 or maybe 15 | 0 is your best best.
