How do I find a job 3 years post-college with unrelated experience?

I graduated with my bachelors in economics from a top us school (not that it matters in this economy) and I have been working odd jobs in education ever since. Within those 3 years, I worked part-time and went to school part-time. I was in graduate school for computer science but ended up dropping out bc l couldn't afford it anymore and the market is horrible. Now, I wanna go back to my original plan and do a financial role. I feel like my resume sends a lot of red flags because I don't have any relevant or full-time experience. I don't have any internships or clubs. I spent only my senior year at my university (Covid + transfer) so I didn't really get involved in anything. But no excuses, I probably could've tried harder. I can't even get an accounts payable job or anything with my local branch banks. I've tried government for months but they're on a hiring freeze. I'm actually in the process of applying for military officer school but it's a very long process and not guaranteed so I need a full-time job just in case. How do I get started?
