Of the options you provided, "provide feedback" seems like the only appropriate one since the other two are too specific and don't seem like opportunities to provide positive feedback.
I would phrase it as "Have something to tell us?". This is generic and would be recognized as an opportunity to ask about a problem, complain about the experience, or praise the experience. Additionally, answering this an easy question for a user to answer and might do a better job of hooking the user into the feedback flow. By the time the user has finished reading "have something to tell us?" they've already answered the question automatically and only need the minimal effort of clicking the button to communicate that initial answer. "Provide feedback" requires more effort for the user to answer, and no one likes to deliberate more than they already have to.
A better answer would cite A/B testing results on the verbage that produces the most feedback. This answer is just my opinion
