Answer 1

If I understand your requirement correctly, then you should go to your content type Manage form display configuration page, it should be under: /admin/structure/types/manage/YOUR_CONTENT_TYPE/form-display
Then you should disable Authored by and/or Authored on by dragging them to the disabled area in the table, then click save

Answer 2

The information about "last saved" and "author" is under meta in form variable.
To remove it, you need to alter form and unset these variables.

function MY_MODULE_form_alter(&$form, \Drupal\Core\Form\FormStateInterface $form_state, $form_id){
  if($form_id == 'node_CONTENT_TYPE_form'){
    unset($form['meta']['changed']);
    unset($form['meta']['author']);
  }
}

Answer 3

The following worked for me:

    function MY_MODULE_form_alter(&$form, \Drupal\Core\Form\FormStateInterface $form_state, $form_id){
  if($form_id == 'node_CONTENT_TYPE_form'){
    $form['meta']['#access'] = FALSE;
  }
}

Answer 4

I had the same problem with claro and a group content node edit form. These did NOT work https://www.drupal.org/project/simplify/issues/3207027 https://drupal.stackexchange.com/a/134540/14822 (partially worked - empty right sidebar still displayed)

what worked for me was i. create a custom module and implement form alter like this

use Drupal\Core\Form\FormStateInterface;

/**
 * Implements hook_form_alter() for node form.
 */
function mymodule_form_node_form_alter(&$form, FormStateInterface $form_state, $form_id) {
  $current_user = \Drupal::currentUser();
  $roles = $current_user->getRoles();  
  if ( in_array('administrator', $roles)) {
    return;
  }
  $node = $form_state->getFormObject()->getEntity();
  if ( !in_array($node->bundle(), ['mycontenttype','myothercontenttype'])) {
    return;
  }

  $form['#attached']['library'][] = 'mymodule/mymodule_simplify_node_edit';
}

Then create a mymodule.libraries.yml file and declared this library

mymodule_simplify_node_edit:
  css:
    theme:
      css/simplify.css: {}

This allowed me to inject css for this form. Since security is not an issue and I only wanted to simplify the form for basic user this is ok.

these are the css rules i used to fix the problem

.layout-region--node-secondary {
    display: none !important;
}
.layout-region--node-main .layout-region__content, .layout-region--node-footer .layout-region__content {
    max-width: 80rem !important;
}
.layout-region--node-main {
    float: none !important;
    width:  100% !important;
}
