They most certainly do.

On extended keyboards, Home and End are dedicated keys. Home scrolls to the start of the document; End scrolls to the end.

On laptops and other reduced keyboards, Fn-left arrow gets you the Home key, and Fn-right arrow gets you the End key.

I don't know when you last used Mac, but Cmd-left and Cmd-right have been consistent at least within apps that use Apple's guidelines for many years.

It's important to remember that your expectations for how these things should work are not based on some universal Platonic ideal, but rather on how Windows did things, so when Apple does them differently, that's not some objectively heinous violation, but rather a different decision based on different preferences.
