I recently undertook a similar direction (moving from track to blended GT use) with my build. I kept the CSG spec Flex A's and OEM wheels with Champiro SX2s because I haven't completely given up on track days (don't @ me for the heavy wheels). Ride quality wasn't the issue if I set them to soft. I mention the setup because it's not particularly "GT" oriented.
Sound insulation did wonders for livability: My wife and I can (at typical LA highway speeds) converse in normal voice/tones on the 405's awful pavement. I can cut the stereo volume in *half* for podcasts. Specifically, adding killmat to the fender liners and to the trunk side of the parcel shelf shifted the road noise farther away (lower) from the high pitch frequencies that give human speech intelligible meaning. I'm not sur the actual Db reading is lower-- but it feels a LOT lower.
For a project with 2/10 difficulty and costing <$100, it's something I wish I'd done the minute I got the car.
Pro: I can hear myself think. Car feels genuinely more calm to drive on my commute. Exhaust drone is cut WAY down (fold the seats when I want to hear it).
Con: Weight. I can hear myself think.
