So, I know this cooling thing brings up some pretty heated debate for whatever reason so I will share what appears to be a fix for me. What I found to work was increased coolant flow and a lower thermostat setpoint.
The only change I made was going from a standard parts store 185° thermostat to a high flow 160° thermostat and it now goes no higher than 160 ever. I retraced the route from the trip I took that prompted the original post and instead of hitting over 200°, it stayed at 160°.
160 gives me peace of mind. Maybe 200-210 is an acceptable range, I'm not here to argue that but I drive my car for fun and relaxation and staring at the temp gauge sitting that high is not relaxing to me.
Thanks all for your input on this post!
