According to this site for $args to use https://www.billerickson.net/code/wp_query-arguments/

 'meta_query' => array(                  //(array) - Custom field parameters (available with Version 3.1).
       array(
         'key' => 'color',                  //(string) - Custom field key.
         'value' => 'blue',                 //(string/array) - Custom field value (Note: Array support is limited to a compare value of 'IN', 'NOT IN', 'BETWEEN', or 'NOT BETWEEN')
         'type' => 'CHAR',                  //(string) - Custom field type. Possible values are 'NUMERIC', 'BINARY', 'CHAR', 'DATE', 'DATETIME', 'DECIMAL', 'SIGNED', 'TIME', 'UNSIGNED'. Default value is 'CHAR'.
         'compare' => '=',                  //(string) - Operator to test. Possible values are '=', '!=', '>', '>=', '<', '<=', 'LIKE', 'NOT LIKE', 'IN', 'NOT IN', 'BETWEEN', 'NOT BETWEEN'. Default value is '='.
       ),
       array(
         'key' => 'price',
         'value' => array( 1,200 ),
         'compare' => 'NOT LIKE'
       )

So following the above example I would maybe try something like this and add as many keys as you need to in order to search all the taxonomies you want.

$args['meta_query'] = array(
            array(
                'key' => my_key_1,
                'value' => $args['s'],
                'compare' => 'LIKE',
            ),
            array(
                'key' => my_key_2,
                'value' => $args['s'],
                'compare' => 'LIKE',
            ),
            array(
                'key' => my_key_3,
                'value' => $args['s'],
                'compare' => 'LIKE',
            )
        );
    
        return $args;
