I played with xinput settings for a few reboots, but no change.
However, I was able to discover a setting that helped me: chrome://flags/#windows-scrolling-personality
Once enabled and after a relaunch, websites with small fonts and tiny code now scroll at a much reduced rate, greatly improving this issue.
It’s worth noting that the touch pad on my laptop scrolled very smoothly as fast or slow as I liked; it was just the scroll wheel on my physical mouse that had this ‘issue’ for me.
