Optimizing financial future as a HS student

This post is likely very unusual for this sub but I have been reading through here and found the advice very helpful. I have just graduated high school and have been accepted into a BS/MD program which gives me guaranteed admission to medical school given I meet GPA requirements (3.7 and no MCAT). Recently through this program I was also able to get a full cost of attendance scholarship for undergrad and medical school.

I am extremely grateful to be put in such a situation and the lack of debt has lead me to think about my financial future. What can I do over the next 8 years to optimize my finances? Should I get a job, invest, etc.? Are there any choices I could make today or in the next couple years that will help my future self?

I understand that I should take the next 8 years to study, learn, and become the best doctor I can. But given my lack of stress for medical school admissions and debt I was wondering what else I could do to set myself up.
