Do you now speak French? If not, you’re going to have a bad time.
Edit: Just to add, Paris is an international city where one can get by without speaking French. However, building a life and assimilating to a point of feeling local (and not an outsider) will require French. If one doesn’t speak French, this is the best opportunity to start learning and practising. Taking in-person lessons with others is a good step towards building a local network. Also, signing up for hobby groups helps one meet people with similar interests.
