If u simply want extra time, u can join the Lichess chess960 team (I'm not advertising; its a sort of personal opinion). They host a lot of tournaments with different time controls. Sure, they also host tournaments having rapid timecontrol, such as 10+5, etc.

Sorry, but u have to make ur move within the first 30 seconds in order to prevent the game from being aborted.
