Regarding dragging, macOS also has an "accessibility" option to drag with three fingers. (It used to be a regular trackpad setting.)

It is a rather obscure feature, and yet it has such a dedicated following (me included) that a re-implementation of it was recently merged into libinput. The downside is that tap-and-drag is disabled when three-finger dragging is enabled, which makes it a bit harder to go back and forth across operating systems.
