Is there any good literature on the risk of secondary spreading by individuals who are IgG positive (hence presumably immune? If you are IgG positive, would it be safe visit family in endemic states like Florida, or Georgia?

Your IgG class switching can make this identifiable 4 days after infection but typically by day 15. Read the Nature article on it: Serum IgA, IgM, and IgG responses in COVID-19 IgG by itself is useless, needs to be in the context of IgM to even begin mapping post infection timeline.
