From what you describe, the home-helper role may give you some insights that would be important in your development as a physician depending on what circumstances you are exposed to. I am pleasantly surprised you didn't jump into the "crisis text line" roles that many applicants found. If I had suggestions, I would say that finding opportunities to work with sheltered communities (LGBTQ+, developmental disabilities, or women/children) could serve a strong contrast that leverages your interest in mental health.
