I only use trackpad too, and there are a couple of things to know:
In SketchUp you would do control-command-drag to start an orbit going, but you don’t have to keep the keys held down. You can switch in and out of pan by pressing the shift key.
In LayOut you are immediately in the orbit tool, you only have to press shift to pan.
Something else, in accessibility I have it set to treat three fingers on the trackpad as a press, that means I can do delicate movements of things without having to do a mechanical press downwards. It’s a very gentle way of working.
Also, once you are orbiting after using three fingers to start that, you can release two fingers, and with a soft stroke of the trackpad with one finger you can continue to orbit or pan.
