I have Bontrager Select Invert 35c on my Bianchi Strada and the ride is oh so comfy, yet corners well at high speed on damp roads.
If you're gonna go cross, go cross, not cross-like with calipers.
Forgot to answer your questions... I'd definitely rate a Bianchi Volpe a good value considering it's drivetrain and durable steel frame. If lightweight for you means 21-22lbs then it's great too. Bike companies are no longer listing weights for some reason but I think the Specialized's, Treks, and Bianchis in that price range have roughly similar weights. You may want to do centurys on narrower tires than 35c, but only a cross bike will let you have 35c's in the first place. Comfort for a century, or general riding for that matter, will depend on riding position and your flexibility. For $900, I'd consider the Fuji Cross (I've seen on sale), Bianchi Volpe, or Kona Jake.
