In late 2018 I tried a friends CX bike with 30mm Schwalbe Pro One tires, and that convinced me it was time to go wider. Now I use 30mm Schwalbe G-One Speed tires on 30mm wide hoops(23mm internal width). They blow up to be about 31.8mm wide, and the ride is smooth and fast. Unless I start TTing again, I'll never use narrow tires again.
