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.

I'd rather use more modifiers than reach for a key that's far away from home row. ctrl-a/e for start/end of line works pretty much everywhere.

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.

On a related note, I've half-seriously considered wiring up a switch pedal[1] as a modifier key in Emacs through MIDI.

Where I really want chording to be universally available, though, is in video games when playing cross-input games on controller.
