What sentence do you think is written correctly?

1. It is me who am wrong.
2. It is I who am wrong.
3. It is me who is wrong.
4. It is I who is wrong.
In my opinion, I think 2, 3 and 4 are all correct, but 2 will be the most formal and archaic, 3 will be the most casual and 4 will be used in a formal context nowadays. It is just my speculation, how about you? Thank you very much!
