Answer 1

You can try with something like this:

use Symfony\Component\Form\Extension\Core\Type\ChoiceType;

/**
 * @inheritdoc
 */
public function configureFormFields(FormMapper $formMapper) {
  parent::configureFormFields($formMapper);

  $subject = $this->getSubject();
   if (null === $subject->getId()) {
     $subject->setType('permanent');
   }

  $formMapper->add('type', ChoiceType::class, [
    'label' => 'config.label_type',
    'choices' => [
      'config.label_permanent' => 'permanent',
      'config.label_automatic' => 'automatic',
      'config.label_temporary' => 'temporary' 
    ],
    'required' => false
  ]);
}
