Add Meta Fields to Specific Page(s)

Is there a way to add fields to specific pages like the home page?

I did try using the slug with no luck

function wcd_tradie_theme_page_meta_boxes( $meta_boxes ) {
    
    global $post;
    $frontpage_id = get_option('page_on_front');
    $post = get_post($frontpage_id); 
    $frontpage_slug = $post->post_name;
        
    $meta_boxes[] = array(
        'title'      => __( 'Call To Action', 'wcd-tradie' ),
        'post_types' => $frontpage_slug,
        'fields'     => array(
            array(
                'id'   => 'cta_title',
                'name' => __( 'Title', 'wcd-tradie' ),
                'type' => 'textarea',
                'std'  => __( 'HELLO & WELCOME', 'wcd-tradie' ),
            ),
        ),
    );
    
    return $meta_boxes;
}
add_filter( 'rwmb_meta_boxes', 'wcd_tradie_theme_page_meta_boxes' );
