I also hate the default setting.

I changed it to uh, left thumpad moves the mouse, left thumbpad click is middle click, remap the right pad to be 4 way buttons, top and left to left click, bottom and right to right click.

Moved scroll to L2 and R2, or you could map them to up and down on a joycon, or the dpad, or L1 and R1, etc.
