  1. It will require a little bt of code along with ACF

    Add checkbox field (ex : brands) and add following code in your functions.php file 

    function my_acf_load_field( $field )
{
    global $post;
    $field['choices'] = array();
    wp_reset_query();
    $query = new WP_Query(array('show_posts' => 100));
    foreach($query->posts as $product_id=>$macthed_product){
            $choices[$macthed_product->ID] = $macthed_product->post_title;
    }
    $field['choices'] = array();

    if( is_array($choices) )
    {
        foreach( $choices as $key=>$choice )
        {
            $field['choices'][$key] = $choice;
        }
    }
     wp_reset_query();
    return $field;
}
add_filter('acf/load_field/name=brands', 'my_acf_load_field');

    use wp query parameters to filter posts.

    Post id will be the checkbox value with title as label in metabox.
