typed out an response earlier today but lost it on my phone, so take 2

ya, get ya on time constraints for work etc, and this is why given your route, super tough tires are going to be the way to go. I check for glass after i ride over it cuz it doesnt happen often, and i know its worth the 1 min to do both wheels rather than the X mins it takes to fix a flat, by a long shot.

re armadillos, i had a pair 26x1.5 on my commuter mtn bike for years and years, with hardly any flats in donkeys years. They do have a very stiff sidewall, so they ride hard, I finally changed them to some regular marathons that were more supple (ha some of you say, thats an oxymoron) compared. The armadillos had maybe 7 or 8 years on the bike, still had life in them and I ended up giving them to a neighbours kid for his commuter and they lived on.
I presume they still make them, but from my experience , they were pretty tough
