Will a dismissed shoplifting charge ruin my future?

I'm going into my Junior year right now with a 3.7 and strong passion for investing. However, three months into being 18 I went to my unis mini market and was buying some food and a protein bar. I bought everything, but had my protein bar on counter that evidently didn't get rung up according to the cameras and log. I get an email 7 months later from the school pd and am charged with shoplifting of $5.60. The only reason they identified me was because I purchased items. I went to the school legal advice on how I could get this off since I was buying my items and she told me that I could get it dismissed...

Well f*** me because I took the pretrial diversion and months later find out what an awful decision that was. According to the FDIC I can't work in any FDIC insured firm for 5 years(think banks). And I of couse got this charge in a state that doesn't allow expungements...However even with the short term ban from banks, I can still go to the buyside I'm pretty sure. How little of a chance do I now have even with eligibility though?

I have been investing in my own portfolio and trading, studying books since I was 17 and am now 20 wondering if I should still pursue this field. It was a misdemeanor for petty theft and all charges are dismissed. ALSO TO NOTE, I was never fingerprinted or had pictures taken. If that matters. I am willing to take any steps to get into PE, Hedgefunds, or anything else I am still legally eligible for. But am afraid that I am now shut out of the financial world.

-----------------------------------Questions----------------------------------------- Will fingerprint background checks still find my record? I can still find it by searching my county records, but wonder if it will show up on their national level check.

When should I disclose this information when applying for internships/jobs?

Can I still get licenses such as Series 7, 63, etc.?

Is it just money handling positions, or does this FDIC rule mean everything like research/analyst positions are off limits?

Would it be possible that I can still do internships as it isn't full time employment?

Thanks guys, really appreciate any responses. This means a lot to me as I can't pay for any legal advice.
