Progress.

With this code in functions.php I can get the AND posts; that is, posts tagged with “Toronto” AND posts that have “Toronto” assigned to the meta_city field.

I need the “OR” of course. Still searching. All feedback is welcome.

add_action( 'pre_get_posts', 'md_modify_tag_archive_to_include_acf_fields' );

function md_modify_tag_archive_to_include_acf_fields( $query ) {
	if( $query->is_main_query() && $query->is_tag ) {
		$term_name = $query->query[tag];
		$term = get_term_by('name',$term_name, 'post_tag');

		$meta_query = array(
			'relation' => 'OR',
			array(
				'key' => 'meta_city', // name of custom field
				'value' => $term->term_id, 
				'compare' => 'LIKE'
			)
		);
		$query->set( 'meta_query', $meta_query);
	}

}
