It sounds like you are looking for something low maintenance but still has the characteristics of a lawn. Dog Tuff grass might be perfect for your needs. https://plantselect.org/learn/dog-tuff-grass-everything-you-need-to-know/
I have wooly thyme between flagstones and it does well there. It spreads well, is drought tolerant and does stand up to light foot traffic, but I loose some every every winter. Rupturewort struggles in our winter climate and might not winter over well.
