Sound insulation in 2017 Chevy Cruse LT

I've noticed some road noise at highway speeds, particularly over asphalt roads in my 2017 Cruze LT, leading me to crank the stereo volume more than I'd like. I've started investigating soundproofing insulation in the doors and/or floor mats. Can anyone share their experience doing something similar in their Cruze? Curious if you've found it to be worth the cost and effort, or have any tips to share.tweakbox...
