I've got a Logitech Ergo M575, and an Elecom Relacon handheld trackball that I toss in my bag for when I'm working from outside the house. I like the Relacon as a travel device vs. a larger trackball or small mouse because I can move my arm, hand, and wrist more, and more naturally, and still have the same control. I often find myself holding it across my chest or waist, and I can even type (not quickly, but still) while holding and using it. The buttons feel like the shoulder buttons on a Switch joycon, so there wasn't that much of a learning curve.
