If it were me, I would go for either the Pinarello Prince or the Parlee Z1. I think the Cervelo is more of a hard core race bike and may not be as good a choice for non-competitive cyclist.
I know someone that owns a Prince and tells me that it is fast and rides very smooth. The Parlee can have custom geometry if you want it. Parlee have a reputation of being fast and comfortable. A couple of other bikes that you may also consider are Crumpton and Calfee, which would be similar to a Parlee.
