I really like the Logitech Slim Folio case with a separate small bluetooth mouse for when I need it. 98% of the time the trackpad would just be taking up space that I'd rather fill with keyboard. The times I do need a mouse, I probably want a proper mouse rather than a trackpad.
The different remote desktop apps (VNC, Nomachine, etc) have ways to translate touch events into mouse pointer movements/clicks. Not what you'd want to use for a serious CAD session, but fine for little things here and there to save pulling out the mouse.
