How to conditionally display custom fields in template overrides

I am using the following code to pull in some custom fields into an override of com_content > category > blog_item.php:

[code] $video = $this->item->jcfields[4]->value; $media = $this->item->jcfields[8]->value; [/code]

Further down in the file, I have added the following blocks of code to perform some conditionals:

<?php if(isset($media) && !empty($media)) : ?>
  <!-- Media custom field output -->
  <div class="media-block">
    <?php echo $media; ?>
  </div>
  <!-- Media custom field output -->
<?php endif; ?>

For some reason the if conditionals are not working as expected. The Media custom field output block is always being displayed, even if the custom field has no defined value in the database.

Is this an issue with the implementation of the custom fields in the override or something else?

In Joomla 3, I was using the following for adding custom fields to com_content template overrides:

JLoader::register('FieldsHelper', JPATH_ADMINISTRATOR . '/components/com_fields/helpers/fields.php');
$context = 'com_content.article';
$article = $this->item;
$fields = FieldsHelper::getFields($context, $article, true);

foreach($fields as $field) {
  $fields[$field->name] = $field;
}

<!-- Media custom field output -->
  <?php if(isset($fields['media']->value) && !empty($fields['media']->value)): ?>
    <?php $class = $fields['media']->params->get('render_class'); ?>
    <?php echo $fields['media']->value; ?>
  <?php endif; ?>
<!-- Media custom field output -->

I prefer the shortened version for Joomla 4, and would like to keep using it if possible.

Cheers,
