Adding template suggestion for twig based on page and content type
Try this out:

/**
 * Implements hook_theme_suggestions_page_alter().
 */
function myModule_theme_suggestions_page_alter(&amp;$suggestions, $variables) {
  $node = \Drupal::routeMatch()-&gt;getParameter('node');
  if ($node instanceof \Drupal\node\NodeInterface) {
    $suggestions[] = 'page__' . $node-&gt;bundle();
    $suggestions[] = 'page__node_' . $node-&gt;bundle();
  }
}
