tldr: Say no to switch toggles. Say yes to checkboxes. (Unless you are Airbnb)
Switches
Switches can be ambiguous about their state and their intent.
IRL, they are usually vertical
Which side is on?

Or labeled for choosing modes
They don’t do RTL well
Using an RTL language? Which is the on side—turned to the right, or to the left?

The accent colours on the switch are a helpful clue.
But the colours can’t help when Digital Wellbeing turns on the grayscale mode.

But Google uses them
Yes, they do. They also appear to be learning the folly of their ways. Check out these screenshots from upcoming Android 12:

Checkboxes
If it’s filled, it’s on. If it’s empty, it’s not.
There’s no right, left, up or down. Language doesn’t matter. Colour doesn’t matter. No ambiguity1. No confusion.
