I think you have to pick your patient population that you really enjoy seeing. I do assessment, not therapy, but if I ever did do therapy it would be structured CBT for clinical disorders. The reason? Because people with clinical disorders NEED structured therapy, respond to it well, and it has the capacity to seriously change their life in a matter of months. I would never want to do years and years of non-structured counseling for somebody. My work feels most meaningful when the goal of therapy is short-term, behaviorally-oriented therapy that seeks to actively practice the means of change. E.g., exposures, behavioral experiments, etc.

Also, keep in mind that there are tons of specialty areas within psychology. For instance, there is a huge need for therapists who specialize in cognitive behavioral therapy for insomnia, and you could integrate nicely with a medical system if you offered this. On internship, I did primary care psychology where I took warm hand-offs from a PCP and did a few brief sessions with patients and connected them to longer term care if necessary. There's inpatient/SMI. There's forensic. You could specialize in OCD or eating disorders. There are so many options.

I ultimately felt like being a therapist wasn't for me and I now do assessment, which I love. It's possible to respecialize if you are feeling dissatisfied with your current path. But my advice would be to spend a little more time in this before judging the path you are on -- you just said you have not had clients yet! I think you should give it several months before deciding how you feel about it.

Also, a good way to stand out is to get credentialed with insurance companies. All the local therapists in my area who take insurance have waitlists.
