I ultimately chose Prism for background / history, longevity, and activity of the project. Be sure to check them out if Prism doesn’t suite your needs. I looked at a few different Mvvm projects - MvvmLight, FreshMvvm, Mvvm Cross, just to name a few. I had done some research on Xamarin Forms, and decided I would bring in Prism (and utilize Unity for IOC / DI). As soon as I received my Macbook at the new job, it was go time.
