I’m living in Europe now and would like to share my experience with this:
When you proceed to pay, the machines here have 2 options side by side on the screen for you to select how you want to pay - cash at the counter or card at the machine. So I’m quite surprised that your machines work differently
Quite a few European countries actually still rely heavily on cash to the point of cash-only for a lot of shops, for example in Germany and Italy
Besides your list, one other advantage I found was being able to order overseas when the locals didn’t speak English at all and I couldn’t read the menu. In Norway, there’s an option to select English or Norsk. In Poland where I went, there wasn’t a choice but it didn’t matter because the menu is mostly universal so the pictures were sufficient
