I suspect the future lies in terraforming nearby planets rather than going hundreds of light years in search of a good fit. Mars alone could house 2 billion people, and Venus is almost as big as Earth. If we can develop a stable enough society to alter these planets over the course of decades and centuries, we can begin thinking about Alpha Centuri later.
