I'm leery of that sort of definitive power ranking becoming explicit in-universe, because it will be impossible to be very consistent with it.
Characters are generally as weak or powerful as the writers need them to be in any given scenario. The more powerful "on paper" that you make them, the more backflips you have to do as a writer to create drama and worthy adversaries.
It's kind of fascinating in the context of WANDAVISION, because Wanda's biggest opponent here...
... is probably, essentially, herself.
