I’ve never even seen a single screw like that here in Canada. We mostly use Robertson bits (square hole) which was invented in Canada and laugh at the US for the little feud with the Ford motor company that eneded up with them using the Philips bits (plus shaped hole) for their stuff. But then all their culture leaks over here anyway and most things use Philips anyway. Construction is pretty much all Robertson.
I’ve used Robertson a few times. They’re quite nice, and I prefer them over philips, but its strength is also it’s weakness: The square hole allows for a lot of torque, but punching that square weakens the head and makes the screw head more likely to shear off.
