My 200 is my everyday car/truck and our weekend vehicle to go skiing. I have only a 20 mile commute. The mileage is terrible but I certainly feel safe in it with the family. 20 years ago when I did drive a Civic coupe there were far fewer Escalade ESVs, Suburbans, Danali XLs, Navigators on the road. At least now I'm of equal mass.
The Land Cruiser on the Highway is a pleasure. I'm not sure what suspension you have. If you feather the throttle you can manage 18 mpg. Don't expect much more. I avg 12mpg with mixed driving. The 13 has synthetic so you can stretch your oil changes a little. Not sure what Toyota recommend for Synthetic. I do 7,500 with Mobil one but if it goes over I'm really not concerned. The oil at 7,500 looks new. Crystal clear. If you're not sure use Blackstone and have in anayzed. Make sure your alignment is perfect so you don't eat tires. Park in a spot away from idiots.
I'd say buy a $10,000 toy that you can enjoy on the weekends or drive to work once a week on really nice days. Even better, buy a toy that both you and your wife can enjoy or take a couple vacations. The mileage does not depreciate the LC as much as lesser vehicles. I'd consider anything under 100K and less than 6 years old not broken in yet.
Best of all you'll look forward to your ride home and your baby. If there's traffic, pull over, reach into your cool box and crack open a drink, "for emergency use only." Civics don't have this useful feature.
If you love it, drive it.
