Macs have every one of those, just with different shortcuts: https://support.apple.com/en-us/102650

Sure, but using modifier keys. What if I want to add shift to the mix to select, let's say to the beginning of line or document? You'll need to press two modifiers. That's not optimal. And I use these all the time while editing.

And I don't consider this a MacBook flaw particularly, it's more or less general laptop flaw nowadays. If anything, other manufacturers have even more imagination to mess up keyboard layout.

		Eh, I dunno. I played piano, so I'm not allergic to pressing 10 keys and a couple of foot pedals at once if needed. Here, that means I rarely consciously think about what chord I'm pressing to select from here to the beginning of the word/line/document.
