Paragon suspension fork fits your bike as-is and is an upgrade for sure. I have a dual air Sid XX; its the real deal.
Note, the manufacturer took the time to spec a custom fork crown to aesthetically match your headtube size.
Fork swaps are expensive in tooling; chances are you are not going to do this yourself, ask the shop that will do the work what forks they can get.
Not too sure the OP will like the Paragon as an upgrade. I believe (might be wrong), the NCX fork on that Cannondale is an air fork....I think:

If Cannondale installed an airfork, the OP might not feel much of a difference between this and the Paragon. If it is a spring fork, then there will be a big difference and be a bit confusing as well as why a $1250 bike that is as nice as that Cannondale has a spring fork.
If the OP really doesn't like the fork on this bike, it might be a good idea to sell bike and purchase a bike that does not have suspension.
