The Value is stored in database. The Label is what users see. If they're no different then you don't need to specify Label as Value will also act as Label. To translate you need to add a language string for the Label (if there is one, otherwise Value) to your CB language files. Example based off your strings as follows.
'English' => 'English',
'German' => 'German',
'French' => 'French',
See the below for further language usage information.
