Thanks for the review, @StefanieSenger. Before I touch the validation, could you confirm what you have in mind? Looking at the current code, estimate_bandwidth already uses "random_state": ["random_state"] in @validate_params, and its default is the integer 0 (the docstring fix just corrects default=None to default=0). check_random_state accepts only None, an int, or a RandomState instance, so I don't see a string value that the function would accept — the one place StrOptions is paired with random_state (TargetEncoder) is specifically the deprecation sentinel "deprecated", which doesn't apply here. Am I missing a case where a string should be valid, or did you perhaps mean a different change? Happy to add it once I understand the intended constraint.

Sorry @Kropiunig, not sure what I meant there. Your PR is good to go as is.
