One configuration I always immediately make is enabling three-finger dragging, along with tap-to-click. Significantly reduces the friction (both literal and figurative).
I've found that many Mac users aren't aware of the three-finger drag and select feature, and it seems Apple has somewhat hidden this setting for some reason: https://support.apple.com/en-gb/102341
With tap-to-click, my touchpad is completely silent.
I don't have a MacBook but I looked up a video and this seems interesting. But how does it solve the problem of hitting the edge of the trackpad? If anything, it seems like it makes the problem worse because now you have three fingers on the trackpad so you will hit the edge quicker.
The gesture is "sticky" when moving objects: you can lift your fingers long enough to move them to the other side of the trackpad to continue dragging.
For selecting text, the trackpad is large enough for nearly any selection.
So I will do my best to explain it, one of the hard problems here is this is just kinda second nature for me. So I may not do a good enough job of explaining it.
But ok so for me, I basically am always resting my thumb (I am right handed if that helps visualize) on the bottom-ish part of my trackpad. So so when I am moving my mouse I have 2 fingers on it. My thumb is just sitting there and my index is moving around.
My thumb is basically my clicking button. It doesn't have to be, but for me it is. It also doesn't have to be at the bottom, I can click anywhere which is nice when I am quickly going from my keyboard to my trackpad and need to click something.
So because I click with my thumb and move with my other finger(s). I can click to drag, select, whatever it is that I am doing with my thumb. And them move with my other finger. With my thumb staying down, I am free to pickup and move my finger as many times as I need. I can pickup my finger for as long as I need to and it will stay selected for as long as my thumb is still there "pressed".
With acceleration that Mac uses, with just a few quick swipes I can easily move a window between 3 monitors.
Since the trackpad is also not physically moving when I "click", it is just pressure sensitive. It also isn't a strain to keep my thumb down.
Oh I get using your thumb to click/hold like it's a button. I was questioning the three-finger-drag but the other comment answered it, the gesture is "sticky" so you can reposition quickly when you hit the edge.
