Of those three, I would avoid the Cannondale with its suspension fork. It will zapp speed to some degree, and it's not needed on streets and paved trails. Otherwise, the Felt and Fuji are very comparable. I'd get on both and see which one sings to you.
Anecdotally, my wife and I were looking at road bikes last weekend as a step up from our Specialized Sirrus 4.0s. I had been drooling over the Trek Domane SL5, and she wanted one as well, until she rode it. She did not like the feel of the fit, and ended up with a Specialized Roubaix that she absolutely loves the feel of even though it was less expensive and the drive train was a step down. Moral of the story - try riding both, and go with your gut.
If you decide to change the saddle on your Raleigh, look at the Specialized Power saddles. They are really nice.
