More buttons isn't always better because there's a limited range of motion that is reasonable for someone to type with. Having a number pad on a laptop keyboard reinforces bad ergonomics because you either need to shift your entire body to the left and have your screen off center or you have a constant and pretty severe lateral deviation in your right hand. As for customizing a keyboard with minimal effort... it's actually easier to do that with MacOS and Windows than it is in linux, in my experience. Sure, you can do basic key remapping really easily in linux with xmodmap but if you want to do anything complicated with the built in keyboard, MacOS has Karabiner Elements which is far better than any of the built in or custom keyboard software like xcape or xkeysnail. Similarly on Windows, AutoHotKey is much easier to do complex customizations as well. I haven't really tried Kmonad but that is cross-platform so it wouldn't really be considered an advantage to linux.
