Regarding your concern about categories, it’s recommended to use the Select 2 UI from the Post Type Form Builder. This is considered best practice for handling categories or location taxonomies, especially if you have a large amount of data.
Simply select the Select 2 UI option from the Post Type Builder, drag your taxonomies into the builder, and click to open the taxonomy settings (See Attachment).
Thank you for your cooperation and patience.
