Your GPA is kind of on the bubble. So, what's your goal program? Are you in the range of their GPA/MCAT stats? If yes, then you probably don't really need the post-bac classes and I would look for a job that both pays the bills and gives you either lab or clinical exposure that matches your goals. Something like becoming a scribe perhaps? Clinical research data management? No shame in McD, but it isn't really getting you the experience you need.
If you aren't quite in the range yet for your target programs stats, then you could look for a post bac that includes EC experience. Or find the healthcare related job and then continue to take a few upper level UG courses as a post-bac student to bump you up a bit.
Best of luck. 🙂
