Any “new field type” devs out there have any success creating a select dropdown?

Trying to do this: Populate post titles in select dropdown. Store the selected post slug as the value.

Utilizing this template. https://github.com/AdvancedCustomFields/acf-field-type-template

Select dropdown working, and posts populating correctly. Getting stuck on the storing of the post slug as value. Any optimization or suggestions greatly appreciated!

function render_field( $field ) {

    $field['type'] = 'select';
    $field['choices'] = array();
    $postTypes = $field['post_type'];

    echo '<pre>';
    print_r( $field );
    echo '</pre>';

    if ( $postTypes ) {
      foreach ($postTypes as $index=>$post) {

        $postChildren = get_posts([
          'post_type' => $post,
          'post_status' => 'publish',
          'numberposts' => -1
        ]);

        foreach ($postChildren as $childrenIndex=>$child) {
          $field['choices'][$childrenIndex] = $child->post_title;
        }
      }
    }

    acf_render_field( $field );
  }

  //this runs after a user hits "Update"
  function update_value( $value, $post_id, $field ) {
    
    $value = "this overrides";
    return $value;
    
  }
