Which one

A Switch takes effect immediately — it is a setting, not an answer. If the change needs a Save button, it should not be a switch.

A Checkbox is an independent yes/no, and several may be true at once.

A Radio is one choice from a set where exactly one must win.

All three take a description, which sits under the label and is wired through aria-describedby rather than being loose text next to the control.
