Answer 1

I think something like this should work.

$args = array(
                'post_type' => 'product',
                'posts_per_page' => -1,
                'tax_query' => array(
                    array(
                        'taxonomy' => 'product_cat',                            
                        'include_children' => true
                    ),
                ),
                'meta_query' => array(
                    'relation' => 'AND',
                    array(
                        'key' => 'meta_field_name_for_brand',
                        'value' => 'meta_value_saved_for_product_post',                         
                    )
                )
            );
$products = new WP_Query($args);
if($products->have_posts()) {

    while ( $products->have_posts() ) :

        $products->the_post();

        the_title();

    endwhile;
}
