The FX3 disc looks like a great bike. My daughter received an FX as a birthday present and it is a nice bike. I can only imagine the FX3 would be significantly nicer.
If you have a local Raleigh dealer, you may want to look at the Cadent 3 or 4. If you buy online, slight assembly will be needed which may cost some money. In addition to that, it never hurts to have the LBS double check everything before you go cruising down a hill at 25+ mph.
This time of year can make things interesting when buying a new bike. The current model year has ceased production. You will begin to find that they are out of stock for certain models. Remaining 2018 models will begin to be discounted very soon if they aren't already.
