Since that is Markdown markup for a table, that line cannot be split in two.

+  a. Use the _FileMetadataManagerInterface::class_ service to prepare

Since that line is part of a list, the second line must be indented.

+  foreach ($my_file_metadata->getSupportedKeys('exif',

Control structure conditions must go in a single line, as per current Drupal coding standards.

-        $rows[] = ['data' => [$key[1], $x ? $x['text'] : NULL, $x ? var_export($x['value'], TRUE) : NULL]];
+        $rows[] = ['data' => [$key[1], $x ? $x['text'] : NULL,
+        $x ? var_export($x['value'], TRUE) : NULL]];

Code lines are not required to be shorter than 81 characters. Line length and wrapping → , part of the Drupal coding standards, says:

• Lines containing longer function names, function/class definitions, variable declarations, etc are allowed to exceed 80 characters.
• Control structure conditions may exceed 80 characters, if they are simple to read and understand.

(Emphasis is mine.)

   public function __construct(

{@inheritdoc} is not used in documentation comments for constructors.
This makes me wonder: Was {@inheritdoc} correctly used for the methods that can use it?

+  /**

+   *   The module handler.
+   * @param \Drupal\Core\Config\ConfigFactoryInterface $configFactory
+   *   The factory for configuration objects.
+   */

The description for a constructor must start with Constructs a new followed by the class name (including its namespace), and end with object.

+  /**
+   * Module extension list.
+   *

A definite article is missing in the description.
It is not a list, but a service.

Since that is Markdown markup for a table, it should not be changed.

The existing text is already correct.

-2. __Use a known local temp copy of the remote file to avoid remote file access:__
+2. __Use a known local temp copy of the remote file to avoid remote 
+file access:__

Since that text is part of a list, the second line should be indented. Then, since that line should be bold, I am not sure it can be split on two lines.

+    $this->assertNull($file_metadata->getMetadata('exif',
+    [1, 'imagedescription']));

If the code is going to be split on two lines, the second line must be indented too, to make more evident that array is an argument of $file_metadata->getMetadata().
Also, the parentheses should be placed on a new line, which is what has been done with the next changed lines.

+    $desc_tag = $this->container->get(ExifTagMapperInterface::class)->resolveKeyToIfdAndTag([1,
+      'imagedescription',
+    ]);

That is the correct way to format the code.

+   * Constructs a new FileMetadata Object.
+   *
+   * @param \Drupal\file_mdm\Plugin\FileMetadataPluginManagerInterface $pluginManager
+   *   The plugin manager.

+   * @param \Drupal\Core\File\FileSystemInterface $fileSystem
+   *   The file System.
+   * @param \Drupal\Core\Config\ConfigFactoryInterface $configFactory
+   *   The config Factory.

The method description is missing the class namespace.

+  /**
+   * {@inheritdoc}
+   */
   public function __construct(string $message, string $plugin_id = NULL, string $method = NULL, \Exception $previous = NULL) {

{@inheritdoc} is not used in documentation comments for constructors.
The description for a constructor must start with Constructs a new followed by the class name (including its namespace), and end with object.

+  /**
+   * Module extension extension.
+   *
+   * @var \Drupal\Core\Extension\ModuleExtensionList
+   */
   protected readonly ModuleExtensionList $moduleList;

The property description is not correct.

Addressed #7. Please review.

Patch #9 applies cleanly and solves most of the issues. The only ones remaining are:
