On an iPhone, most people will use their right thumb to toggle a switch, so switches are aligned to the right, for easier reach.

On the Mac you’ll use some kind of pointing device to toggle a checkbox, so they are aligned to the left, next to the label, for easier scanning.

But switches in Ventura are aligned to the right, removed from their label. This is purely for aesthetic and consistency reasons, since switches take up much more room. Matching the switch to the label becomes a function of how wide the window is and how many options there are. It makes them harder to work with, both for designers and for users.
