I was going to write you off as one of those weird trackball people, but then I dug into the mouse. It does look like a useful tool for CAD in conjunction with a normal mouse
I also like to turn on "Do not automatically tilt while zooming". I don't recall if that affects SpaceMouse, but I don't like the default automatic tilt when using regular mouse or keyboard navigation.
Also if you are using a ThinkPad, be sure to try each of the three mouse buttons (hold one down and move the TrackPoint around) when not using the SpaceMouse.
