You've made one of the bigger mistakes a freshman can make which is to take Organic Chemistry as a freshman but that weed-out is behind you now so your gpa should take off like a rocket. Major doesn't matter so major in whatever you want that you think you can do well in. Extra points if there is some marketable skills that you can use if you end up needing a gap year or deciding not to pursue a career in medicine.
Could you push research to summer 2022? That's when I see many applicants show their first research activity (summer after sophomore year). At that point you'll have some lab skills acquired in your courses. You need clinical exposure more than you need research although most applicants have both. However, there is debate as to whether EMT is sufficient clinical exposure to suffice. You could get your feet wet with some EMT work and then transition to patient care technician work in an emergency department or inpatient unit (not likely to pay better than tutoring but it gets you clinical exposure in spades). The other alternative would be to do the research during the school year and take a PCT job the following summer.
