For me client autonomy is absolutely massive. I have very strong feelings about the difference in power between client and therapist and always go to see someone who shares my opinion on minimizing the power gap. I think it's very important for Ts to be aware of the power they wield and how even small conversations can affect the therapeutic relationship.
For me, control is very important. I hate not being able to see a clock. I want to be able to make decisions for myself on what is safe to bring up and how much processing time I have. I think that is a perfectly reasonable expectation. I'm an adult and I have chosen to enter a therapeutic relationship. That doesn't mean I have entered a relationship where I have to blindly trust someone else's 'expert' judgement and somehow submit to a way of working that doesn't feel right. I don't think therapists should be viewed as wise, all-knowing experts and most modern therapy is moving towards the therapist taking a far more de-centred position.
The short version of the above is no, I don't think the sense of control you like should be avoided. In fact, I think it should be embraced
