I did use a lot of gestures (especially in browsers, Opera from 10-15 years ago?) but with trackpad you have virtually the same? Single tap=left click, two-fingers tap = right click, cmd+tap = middle click. Two fingers swipe left/right = navigate forward/backward?

What about 2-4 side mouse buttons? What about wheel left/ right motion? What about optional infinite scroll?

I never used those? I usually preferred keyboard shortcuts so laptop (MPB) with hands on the keyboard + occasional use of touchpad for "movement" was more than enough?

Sure, but presumably your original question wasn't addressed to yourself? With a better external keyboard you don't have a trackpad, and even with the internal one sometimes it's more convenient to use the more capable tool
