I find I’m not giving my road bike or mountain bike any love after getting a bike similar to that Fuji. I would put as big a tire on the cross bike, and go have some fun (I’m not sure that bike can go bigger than 35mm in the rear & more room at the front. I’d trade in (sell) the hybrid unless you have a strong need for that type of bike.
Road bikes are generally restricted to well maintained roads (I can’t go bigger than 28mm on mine), and mountain bikes are great if my cruising speed is <15mph. The fuji is obviously a lot more aero and agile.
