This module provides a Form API element to select a Media entity from the Media Library. This element can be used in all standalone forms. I'm currently using this in a Paragraphs behavior form to select a background image with crop-support, but you can use it in a Layout builder form, or a configuration form under "Settings"...

The implementation is borrowed from the Media Library widget and follows its user interface as well as its possibilities:

  • You can limit the allowed media types by passing the machine names of those media types
  • The default value is either:
    • Empty: NULL
    • a single Media entity's ID: (int) 1
    • multiple Media entity ID's separated by comma as a string: (string) 1,2,3,4
$form['image'] = [
  '#type' => 'media_library',
  '#allowed_bundles' => ['image'],
  '#title' => t('Upload your image'),
  '#default_value' => NULL|1|'1,2,3',
  '#description' => t('Upload or select your profile image.'),

I chose to release this as a standalone module so anyone can review / contribute / fork / ... without having to wait on the official core patch (
