The biggest potential pitfall here is you may be limiting your tire width selection. One of the biggest advantages of disc bikes and rims is that they will accommodate nice wide tires and still be aero. Take the new venge for example. You can run 32mm measured tires (28mm labelled tires) on them. To have a rim aero/handling optimized for that tire, you’re looking at about a 32mm outer, measurements not capable with rim brakes.
The rim you mentioned is optimized for measured 25mm tires, which means 23mm labelled tires that balloon to 25mm. Personally, a true 25mm aside from a pure TT is too narrow in this day and age.
When deciding, I would start from the ground up at the tires as that has a huge impact of how the bike will feel. Ask yourself, what size of tire would you like to run, then build from there.
Also, rim brake carbon composition has compromise incorporated in its DNA whereas a disc brake is not held back by limits. The resin for rim brake varieties have to be optimized to resist failure from the heat of braking friction. Disc brake specific carbon rims have a higher modulus carbon that have properties superior to the rim brake version.
IMO, rim brake carbon will be irrelevant in time because there is no consumer material technology that has been able overcome the heat resistance trade offs. Aluminum rim brake builds already rival carbon in performance and looks.
