You will need to get good grades in college in order to apply for medical school. At the medical school I attended, the average GPA is reported to be 3.85, so even one or two B's can hurt your chances of acceptance.
It won't really help you stand out unless you are involved in the publication of a highly regarded article (which takes a lot of luck), try to find opportunities to pursue research.
P.S. right now with the COVID there are many thing uncertain so if you do have to take a halt on your experiences don't worry. You can also check out remote opportunities as well; check out Pointsoflight.org. or OperationWarm for remote opportunities if you are interested!
Best of luck!
