Comment (by Mirucon):

 I've seen several sanitization functions for checkboxes, but they are
 returning only true or false.

 https://github.com/WPTRT/code-examples/blob/master/customizer
 /sanitization-callbacks.php#L12

 https://divpusher.com/blog/wordpress-customizer-sanitization-
 examples#check

 I personally think checkboxes do not need to have custom values and they
 should only be true or false, since they are usually used for switching
 something, like switch to whether displaying tagline or not.

 For the radio boxes / select options, we should have like this function,
 so that only the given choices can be used. https://github.com/WPTRT/code-
 examples/blob/master/customizer/sanitization-callbacks.php#L262
