Consulting criminal history background check?

Got arrested for a fake at 18, felony dropped to misdemeanor (pretrial diversion) then charge dropped and eventually expunged.

I have researched IB background checks, and due to FINRA and FDIC, I would 99% not get a job in IB even though my record is clean after expungement - IB's do an FBI background check w/ fingerprints and that expunged arrest would show up and therefore FINRA and FDIC have my charges on file and I do not meet section 19 minimum requirements due to fake id being a "dishonest" type crime.

So, do MBB/Tier 2 do an fbi fingerprint background check and do you need FINRA/FDIC clearance?
