There is really no fix for the issue you describe. My 2019 Redline with 19's does ride fairly harsh.
My 2016 Equinox LTZ rides substantially better, but they are long gone from production.
About the only way you may find a smoother ride is with a larger, longer wheelbase, heavier vehicle from the luxury brand/category of vehicles. They cater to individuals who value ride quality and quietness over sporty handling and lesser cost.
I'm getting to the same point as the OP; I always liked cars that handled like go-carts; now as I age, I'm not as satisfied with just the handling performance; a little comfort would be nice too!
