Loop through several custom post types to update post_title using a custom field

Hi all. Newbie here. I searched the forum and used this code successfully to update the service post type's post_title using a custom field. How would I rewrite this to support looping through multiple custom post types (service, reviews, portfolio, etc.) and have their custom fields update that specific post type's post_title when a new post is created?

<?php

add_action("rwmb_service_after_save_post", "update_post_title");
function update_post_title($post_id)
{
    // Get the field value
    $my_meta = rwmb_meta("service_title", "", $post_id);

    // Preprare update post
    $my_post = [
        "ID" => $post_id,
        "post_title" => $my_meta,
    ];

    wp_update_post($my_post);
}

Thanks in advance.
