An acd will probably be offered,a pd can probably arrange this. Idk about the backround checks,I was charged with something my lawyer mentioned to me something about trying to get back the fingerprint card or something,the finger print is still in the computer,idk how an acd will deal with that. Since the issue will come up at your job finding a lawyer knowable about these issue might be a good idea. Maybe a lawyer can argue that joint being lite wasn't yours,it may be a long shot.
They already charge you the question is what will the final outcome be,the case can be resloved quickly if you take an acd,it dismiss the charge after a year I think. I think during that time the arrest record can pop up then after a year it is sealed. There is always a chance something may pop up.
