after some digging it appears my first question didn’t matter, the page link field stores the post ID, but there will be a problem if something other than a post is selected, not sure what is stored for those.
$resultLink = get_permalink( $post->ID );
$posts = get_posts(array(
'numberposts' => -1,
'post_type' => 'post',
'meta_key' => 'draw_link',
'meta_value' => $post->ID
));
