Anyway, it's nice to have different settings that suit different people.
If you want it to not scroll further you need to stop scrolling before lifting you fingers. That should be pretty easy to get used to.
The interesting thing: Some Distributions have smooth scrolling (or interial scrolling / kinetic scrolling) by default (Fedora, Ubuntu) and some don't. Those who have enabled it, have no speed setting, so most of the time it's way to fast. I tinkered around a very long time with libinput-config to get it right and now it's acceptable. But it is still waaay better on macOS.
It is NOT a hardware issue though. I tried "hackintosh" on my T460s, and the touchpad experience is nearly as good as on a MacBook, so it is mostly software / OS.
Please don't perpetuate the awful terminological confusion around this issue.
