More ways to customize trackpad usage?

I’m using MacOS and having some issues with using the morph as a trackpad. Specifically, scroll speed is extremely high, even with Mouse scroll speed set to lowest. Is there any way to fix this?

I’m also having some problems with clicking. It’s very easy to accidentally start dragging.

I mapped the up and down arrows to a vertical slider to the right of the trackpad to have smaller increments. But would really like a native option as well.
