A quick run of phpcs --standard=Drupal,DrupalPractice seems to be all good!

Looking through the code in detail I do not see any issues either. Only thing I found was an unnecessary blank line in the form() function in the OptionsGridWidget.php;

    elseif ($property_selected === 'flex') {

      $field_widget_complete_form['#attributes']['data-flex-size'] = (int) $this->getSetting('size');
    }

A single empty line that should be removed is not sufficient to change the status to Needs work. If there is anything else that should be changed, let us report that too.
