What I suggest is the this solution, create a custom template, for your page, in controller pass the data to the twig template.

public function myPage() {

    $data = \Drupal::service('myservice.ran');
    $dataService = $data->getArticles();
    $articles = [];
    foreach ($dataService as $article) {
      $articles[] = [
        'title' => $article->title->value,
        'body' => $article->body->value,
      ];
    }
    $build = [
      '#theme' => 'my_template',
      '#data' => [
        'articles' => $articles,
        'whatelse' => "what esle I want"
      ],
      '#cache' => ['max-age' => 0],
    ];
    $output = \Drupal::service('renderer')->renderRoot($build);
    $response = new Response();
    $response->setContent($output);
    return $response;
  }

then all the data will be available on data in your custom twig template. ( you can change its name to whatever you want).

just be sure you clear the cache when you create your custom template.
