GRX also comes in a 46/30, but as you stated you want speed, going from a 52 big ring to a 48 or 46 is going to have you spin out earlier. These are as BTW, the Shimano cranks. FSA also makes similar cranks. My Cannondale Topstone came with an FSA 46/30, works just fine with a 105 derailer. An FSA Omega ME is $131

But really only YOU know what gearing is going to work so for know I'd pay attention to how often you fine yourself in the 52/11, ask if you need that, maybe do a gear chart to plot out the options.
