In the middle of nowhere (Stafford, England) we have a mix of the lot. Here we have standard crossings that will never be anything but green (for traffic) without a button press. There's also T-junctions here that toggle between multiple roads that insert a pedestrian crossing into the cycle when the button is pressed, otherwise they'll just toggle between the roads as normal. Then we also have Y-junctions where the pedestrian light is green when the opposite road light is green. The buttons might speed up the cycle there but I've never seen any evidence of it doing so.
