1 and 3 are definitely wrong. 1 is wrong for the reason given in the dictionary: staff is a collective noun. 3 is wrong because "an officer" means something different than "someone who works in the office"; it has various meanings in military, legal, government, and corporate contexts, but always means someone in an official role--that is, a role with defined powers and duties. If someone just says, "I am an officer," I'd assume they're a police or military officer.
To me as a native American English speaker, 2 sounds stilted. "I am a member of the office staff" sounds good, if formal. 4 sounds totally natural, but it has a more general meaning, because you're no longer talking about a specific office, which is what you're looking for. "I work in the office of X Accounting Firm" sounds fine, as does simply, "I work for X Accounting Firm," which implies that you're a member of the office staff.
