Mental health treatment doesn't usually have a consensus on how to treat anything. Generally your providers will use whatever methodologies they were trained in, found to be useful, and are themselves comfortable using.

That is not to say that best practices don't exist or standards aren't enforced organization to organization, but mental health treatment is too young a science and people are far too complex to use overly generic techniques.

Additionally, not every patient will want the same things, and not all patients will be be successful with the treatments they are working towards. Some patients will come in for support with gender affirmation and realize that neither gender fits well enough to stop their symptoms, while others don't need anything other than the world around them to stop losing their minds over their choices.

The job of the therapist is to help the patient realize their best possible baseline, and if that involves lifelong issues, prepare them to meet their challenges effectively. It is always a dialogue and a moving target for the patient.
