More easy

    'category_slug_3',
    // Add more category slugs as needed
);

$args = array(

    'tax_query' => array(
        'relation' => 'OR',
    ),
);

foreach ($categories as $category_slug) {
    $args['tax_query'][] = array(
        'taxonomy' => 'category', // Replace with the actual taxonomy name
        'field'    => 'slug',
        'terms'    => $category_slug,

Pages also merge

if ( ! is_admin() ) {
	add_action( 'init', function () {

		$query_data = get_option( 'linkboss_custom_query', '' );
		$post_type = isset ( $query_data['post_sources'] ) && ! empty ( $query_data['post_sources'] ) ? $query_data['post_sources'] : array ( 'post', 'page' );

		$posts = get_posts( $posts_args );

		// Query for pages without taxonomy filtering
		$page_args = [

		$pages = get_posts( $page_args );

		// Merge the results
		$all_posts = array_merge( $posts, $pages );

			echo '<pre>';
			print_r( $all_posts );
			echo '</pre>';
		} else {
			echo '<pre>';
			echo 'No posts found';
			echo '</pre>';
		}
	} );
}

Custom Post Type with Category

// custom post type 'movies' with category
function create_post_type() {
	register_post_type('movies',
		array(
			'labels' => array(
				'name' => __('Movies'),
				'singular_name' => __('Movie')
			),
			'public' => true,
			'has_archive' => true,
			'taxonomies' => array('category'),
			'show_in_rest' => true,
			'supports'     => array( 'title', 'editor', 'author', 'thumbnail', 'excerpt', 'comments' )
		)
	);
}
add_action('init', 'create_post_type');

Custom Post Type Response

function custom_publish_post_function( $post_id ) {
	// Perform custom actions when a post is published
	error_log( 'Post ID: ' . $post_id );
}

// default post type
add_action( 'publish_post', 'custom_publish_post_function' );

// 'movies' post type
add_action( 'publish_movies', 'custom_publish_post_function' );
