Show Only Selected Categories on the Blog Page
Limits the main blog page to posts from the categories you choose, for example only News, while other categories keep their own archives.

Code
// Category slugs to show on the blog page, for example array( 'news' ).
$wpide_blog_categories = array();
add_action( 'pre_get_posts', function ( $query ) use ( $wpide_blog_categories ) {
if ( is_admin() || ! $query->is_main_query() || ! $query->is_home() || ! $wpide_blog_categories ) {
return;
}
$query->set( 'category_name', implode( ',', array_map( 'sanitize_title', $wpide_blog_categories ) ) );
} );Notes
The list is empty by default, which changes nothing. Add category slugs; posts from other categories still appear in their archives, search and feeds.
