You have to not only set the “normal” field value but also the underscored version like this:

  function myAcfGetBlock(
    string $block,
    array $fieldData
  ) {

    $fields = [];
    foreach($fieldData as $fieldKey => $fieldValue) {
      $key = 'block_' . $block . '_' . $fieldKey;
      $fields[$key] = $fieldValue;
      $fields['_'.$key] = 'field_' . md5($key);
    }

    $json = [
      'name' => 'acf/' . $block,
      'data' => $fields,
      'mode' => 'edit'
    ];

    $fields = json_encode($json);
    $acfJson = <<<ACFJSON
<!-- wp:acf/$block $fields /-->
ACFJSON;

    return $acfJson;
  }

so you can then do something like

wp_insert_post( [
        'post_type' => 'job',
        'post_status' => 'publish',
        'post_title' => 'My Jobname',
        'post_content' => myAcfGetBlock('title', [
          'subtitle' => 'My subtitle'
        ])
      ] );
