I agree, the aluminum Grail looks like a nice bike. Perhaps consider the aluminum Cannondale Topstone for a similar price? I think you can get them at REI if you don't have a LBS nearby that sells Cannondale.
Or get the 2020 Trek Domane SL4 with Tiagra. Takes 38's with room for mud clearance.
Or the SL5 with 105, if you can swing it. Get's you full hydraulic 105.
