Best Medical Opportunity for Undergrad

Im in california and Im sort of in a funky situation because my grandpa has offered to pay for my college if i go to u of a but i am worried if i go there i will not have the best research opportunities or preperation possible. Also im not super siked to be graduating from u of a when i have worked my life to do something higher. So im in a sticky situation rn but besides cost what would you say would be the best?
