You asked a very interesting and important question. Missing is some important information. such as your intended major and your intended college which you will attend next year. This would be very helpful to know; however, without that, here is some helpful information.
Here is a helpful story. During my daughter's senior year in high school, the highlight was to be a 3 month internship. Everyone submitted their request, except one girl. This girl wanted an internship with an EMS unit, so she contacted the local EMS unit and arranged with that unit and her school to create her own internship. She ended up being the one who got maximum benefit and enjoyment from the experience. My daughter's and many of the others experiences fell way short of expectations.
Let me know if and how this helps. Best of luck. Keep me posted. I would like to follow your progress.
