Ok, I did it.

I pulled the trigger today. Lynskey is having a huge sale and I've been looking at their bikes for a few weeks so I couldn't pass up the savings. Got a 2018 Lynskey Helix Pro road bike. Traded-in the Cannondale on it. Yes, they take trade-ins.
I upgraded to Ultegra 8000.
I'm keeping the wheels from the Cannondale and swapping them for the Mavic Aksium wheels that are stock on the bike. I'll be flipping the stem too. I'll post pics when I get it. You'll have to be happy with this for now.
