function mytheme_theme_suggestions_paragraph_alter(array &$suggestions, array $variables) {
/** @var \Drupal\paragraphs\ParagraphInterface $paragraph */
$paragraph = $variables['elements']['#paragraph'];

I think it's better to consider the parent already included in $variables this way :

/**
 * Implements hook_theme_suggestions_HOOK_alter().
 */
function mythme_theme_suggestions_paragraph_alter(&$suggestions, $variables) {
  $paragraph = $variables['elements']['#paragraph'];
  $suggestions[] = 'paragraph__' . $paragraph->bundle() . '__' . $paragraph->view_mode;
  $parent = $paragraph->getParentEntity();
  if ($parent) {
    $suggestions[] = 'paragraph__' . $parent->bundle() . '__' . $paragraph->bundle();
  }
}
