ACF with wp-advanced-search

I’m having issues using ACF in conjunction with another plugin, https://github.com/growthspark/wp-advanced-search

I have some code for the form that takes the structure of:

$args['fields'][] = array('type' => 'meta_key',
		'label' => 'Location',
		'meta_key' => 'address_city', 
		'format' => 'select',
                 'values' => array('' => 'Any', 'city1' => 'City1', 'city2' => 'City2', etc... ), 
		 'operator' => 'IN');

For the purpose of the exercise, I need to auto-populate this selector with content from the custom fields. In this case, the custom field is called ‘Address City’. I’ve attempted to do this by creating a function called Cities(). This has been verified by the plugin creator as a viable method.

$args['fields'][] = array('type' => 'meta_key',
		'label' => 'Location',
		'meta_key' => 'address_city', 
		'format' => 'select',
                 'values' => Cities(), 
		 'operator' => 'IN');

My Cities() function looks as follows:

function Cities() {

	$args = array(
                'post_type' => 'property',
                'posts_per_page' => '-1'
     );
   	$inner_query = new WP_Query( $args );
    
    $temp = array(); 
	$cities = array();
	unset($cities);
	$counter = 0;
	
	while ( $inner_query->have_posts() ) : $inner_query->the_post();

			$field_key = "field_53ea04d8b96b6";
			$post_id = get_the_ID() ;
			$field = get_field_object($field_key, $post_id);
			
			$cities[$counter] =  $field['value'];
			
	$counter++; endwhile;
	
	$result = array_unique($cities);	
	sort($result);
	
	foreach($result as $key => $value) {
		$key = $value;
		$a[$key] = $value;
    }
	return $a;

}

I appreciate my code is messy, but I can’t get this to work properly, as the array is not being returned in the correct format. Does anyone have any ideas as to how I can return the array of all fields in the form of:

[value] => [label]

Thanks
