What are the resistant thought form types that my healer friend [name withheld] says she can see in people and finds in me? Would I benefit from her services?

These are not thought forms. They are a portion of your inner belief system, she is seeing, energetically. Negative beliefs, stored in the repository where they are assigned energetically for the linkages between the brain, and the body. Her ability to see this is a gift, but there is a danger in her intruding on the stored beliefs and removing them simply because they are negative. As you appreciate very keenly, there is great utility for many such beliefs, and they all serve some purpose in the dynamics of consciousness for an individual and are best removed via a methodical process of exploration and discovery to tease out their context and their impact within the broader canvas of the person’s identity and desires for improved life experience. So, removing these is not a good idea. We would not recommend that you submit yourself to this kind of surgery, so to speak. It will not benefit you in the way she believes.
