I leave my setup plugged in, using a low-profile USB-C to lightning cable on the iPhone SE stuck on the back of my screen and wired hotspot on macOS is a great experience.
We're discussing a MacBook someday with a built-in phone, the closest I've found is an iOS device wired to my MacBook as a wired hotspot. It's like having fast wifi everywhere.
Using my personal phone (that I also use for other things like calls) wouldn't be like having wifi everywhere on my Mac, for example if I walk away from my laptop while on the phone the Mac would lose internet.
