You have done very well in high school. Congratulations!
What this earns you is mostly two things. One is that you are likely to be very well prepared to start university. The other is that you are likely to have the opportunity to attend a university or college that you want to attend. Specifically, you should be looking for a school that is a good fit for you.
You do not need to attend the most “prestigious” or highest ranked university that you can get accepted to. “Prestige” is mostly to impress high school seniors. Looking for prestige is a recipe that can sometimes lead to a bad result. The rest of us are much better off if we attend a university where we will be happy.
And a highly ranked school can in some cases be stressful, and can in some cases be cutthroat.
And reading your post, it sounds like William and Mary is a good fit for you. Is it the highest ranked school that you can get accepted to? I do not know. I do not care. I would suggest that you should not care either. Is it a very good university? Yes, definitely. Will you get the opportunity to do some research while you are there? I expect that the answer will be a very big YES. Can you get a great undergraduate education there? Definitely YES.
Given your research focus and high stats, I am going to guess that you might eventually end up in some form of graduate program. I know multiple people who have had some sort of biomedical related graduate education (master’s degrees, PhD, DVM, MD, …). They all report that the other students in their graduate programs come from a huge range of undergraduate universities. W&M can prepare you very well for very good graduate programs, as could any of a wide range of other universities.
By the way, I have a daughter who while older than you, might possibly have some common traits, interests and abilities. She also was a very strong student in high school, and had a strong SAT score (although not quite as high as yours). She also was interested in a moderate sized school (and specifically not a large school – UVA for example would have been larger than she was interested in). She also was interested in research. She also did not want a cutthroat environment. She did not attend the highest ranked university that she could have gotten into. Instead she went to a school that was a great fit for her. This has worked out very well. She did very well in classes, got to know her professors, got involved in biomedical research, and graduated with a high GPA, great research experience, and the ability to get strong references from professors who she had worked with and who know her well. Right now she is getting a PhD at a very good university and seems to like it a lot. The other students in her PhD program come from all over the place, including schools ranked higher and schools ranked lower and schools ranked about the same compared to either W&M or the university that she attended. What these diverse students have in common is an interest in research and a history of doing very well at whatever university or college they attended.
You will find other very smart students at W&M. You will not be alone. Actually university in general is likely to give you the opportunity to meet more students who are “like you” in ways that matter, such as being intelligent and taking their education seriously and being interested in biomedical or biochemical research. They might be from large cities. They might look different from you. They might be from other parts of the world. They might have tattoos or piercings. This does not matter. An interest in the same things such as research and education does matter, and is something that you will find among students at any one of several hundred very good colleges and universities throughout the US.
Another issue: You are in-state for W&M, and they do offer some merit based aid. It seems likely to be relatively affordable. You have interests that to me seem to say “graduate school”, of some form or another. Saving some college money for graduate school can sometimes be helpful in the long run.
From what you have said it seems to me that W&M is likely to be a very good fit for you. To me this suggests that there are two reasonable choices at this point. One is to apply ED to W&M, the other is not to apply ED anywhere. Either way you should be looking to attend a school that is a good fit for you.
Rankings are to sell magazines. A good fit is more likely to make students happy and successful.
