Any deviation from that for faster warmup is extra fuel used.* My car has lived 200,000 miles, so I doubt extra wear is a significant factor.

Faster warmup does mean lower fuel usage later in the trip, but at best you get back half of what you spent warming up. Best fuel consumption is to arrive at the other end with the coldest engine you can. Grille block to make it warm up faster.
I see you're from Texas, and I presume is quite different than Poland in terms of average temperature. Low viscosity oil in winter is like a butter (almost) during the coldest part of the year. So cold wear of the engine is a factor here. I'm not saying that your engine will break after few cold starts or EO(ff)C of course, but I'm keeping that in mind.
