What's inside favicon.ico?

Whichever of 16×16, 32×32 and 48×48 you picked — they all live inside the one file, and the browser takes whichever fits the screen.

Why are the larger sizes separate PNGs?

iOS home screens, Android launchers and the two app stores each want their own file, so they can't go inside the .ico.

It's centred on a square canvas at its original proportions — nothing is cropped, and the space around it stays transparent.

No. Everything runs inside your browser and nothing is sent to a server — unless you press Save yourself, which keeps it in your account.
