There was a thread the other day on the sleep board about a just 3yo dropping the dummy and starting to wake early, so you're not alone.
Bribery is a good thing, I think. But it needs to begin with knowing she can do it. There's no point offering a reward for something she can't do, that would just frustrate her and make it worse. So I would save the bribery for now, until you know she can wake up and go back to sleep on her own.
Do you think she still needs needs a comfort mechanism at night? They do grow out of this completely so when I've dropped the dummy it's not been replaced by anything, just not been needed. But if your DD still needs that "Ah that's nice" comforted feeling, then maybe try her with something of yours - unwashed pillow case for example.
If she has grown out of needing comfort to go to sleep, then I'd go for Rapid Return. So very deliberately not sitting with her as she goes to sleep. Being deliberate about your expectations that she will go to sleep on her own in her bed without any fuss.
I would develop a mantra that covers your expectations. For example: "Sleep time now. You stay lying down quietly in your bed at sleep time. Nan night". Have a chat about your expectations during the day and then just go for it, being really consistent and rigid in what you expect.
So for Rapid Return you have to be as quick as you can be to return toddler straight back to bed, repeat mantra, kiss, leave and close door without any faffing.
It's mostly about setting really strict boundaries of expected behaviour: This is what you will do, nothing else is acceptable behaviour, we will keep in repeating this until you accept it
It's a large time investment initially, you might be repeatedly returning to bed over and over again for a few nights. But with consistancy she should get it within a few days. Once you're a few days in and you know she's getting it, that's when I'd introduce the bribery.
