Vantaggi
Decent weather compared to most states. Robust facilities like gym, tennis courts, swimming pool, running tracks, libraries etc. Office of Postdoc Affairs is a strong advocate of postdocs but has limited say.
Svantaggi
The sad state and mismanagement of postdocs in the United States is well documented in many places. Please read about it carefully before committing to it. If you still feel this is the best way forward, then FSU is one of the better places to work. That said, there is no uniformity in the paychecks of postdoc - even within the same department. Faculty are strongly opposed to the idea of higher pay to postdocs due to their own issues with raising grant money. It was a monumental effort to get them to pay for postdoc insurance. Life for international postdocs is vastly more difficult since FSU will not offer support to file for residency. Given that only 10% of postdocs get faculty positions, the remaining 90% will need to search for positions elsewhere and that search becomes astronomically more difficult for international scholars.
