Medicine related extracurriculars to help distinguish myself

I am a junior in a small New Jersey town. I’m an Asian girl with pretty solid grades and projected standardized testing scores who wants to study medicine (most likely to become a nurse practitioner.) A lot of other top kids at my school are going into the medical field as well. How can I distinguish myself from them? I am an officer of the HOSA club at my school, volunteer at a hospital weekly, and went on a service trip the summer before my sophomore year. I attended two medicine related camps the last summer as well.
Becoming an EMT doesn’t seem like a viable option for me because my town’s First Aid Squad is generally no longer open to accepting high school kids. Some of the best kids in my school are EMTs, which worries me! I don’t believe you can become a Registered Nurse Assistant in the state of NJ, so that seems like it’s out too. Would taking online medical courses help beef up my resume? My mom doesn’t think so (she’s very in the college game but is sometimes too confident in a few threads that she reads)

I am getting CPR certified soon, but I want to do more. I know it’s late to pick something up the middle of junior year, but any ideas would be greatly appreciated!
