I have noticed that some CAPTCHA pages, like Cloudflare’s, simply ask you to check a box to proceed. There is no clicking on traffic lights or entering characters. How does clicking on a check box tell them I am not a robot?

Because it measures how your mouse moves to the checkbox. If there was nothing to move to, you wouldn’t move your mouse.
I get the checkbox even on mobile sometimes, I imagine as long as you’re not perfectly hitting the center pixel it knows you’re human.
But that would be easy to program a bit for
Yeah, that sounds reasonable. Touch input is reported similar to mouse input, so it would translate to a touch screen pretty well.
