Probably. Cake and Symfony are further ahead in regards to integration than ZF. In your case, I would think that's a good thing. PRADO is also quite tightly integrated, so if you prefer that style, it's also a viable option. I think that about sums up your candidates -- When it comes to RAD, good documentation and a large userbase are a huge boon, so you definitely want to go with the popular choices.
All IMHO of course.
