Our DD9 has a ritual cup of strawberry milk every night shortly before bed, and she gets really, really upset if she misses it, so that's an easy, daily go-to for us. She recently revived bedtime stories, and I canceled that once last weekend due to behavior issues. We also use early bedtimes, because getting adequate sleep is a health and an educational issue, which are protected rights, but staying up 'til the latest reasonable bedtime is a privilege, and can be revoked.
I'm not sure how we ended up with so many of her go-to punishments revolving around bedtime... it wasn't intentional. It certainly is convenient, though, because we can make sure any intolerable behaviors at any point of the day are met with consequences the same day.
We're pretty flexible and creative with punishments, though, so if something is on hand that's more immediate, we use that. So if DD doesn't want to clean her room, and she has a friend heading over shortly, no problem, play date is cancelled.
