I already mention to you that give us little more details about the plan that you want to do?
Here is the solution that I think it would be helpful for you.
If you want to used map_meta_cap => true then you will need to change capability_type as well with your own type, see more https://codex.wordpress.org/Function_Reference/register_post_type#capability_type
But if you set your own capability_type value then you will need to add capability to users role those you want to add.
here is a complete example.
if ( !class_exists( 'WPSE64458_CPT_Register' ) ) {
class WPSE64458_CPT_Register {
function __construct() {
add_action( 'init', array( $this, 'wpse64458_register_post_types' ), 5 );
add_action( 'admin_init', array( $this, 'wpse64458_add_caps' ), 5 );
add_filter( 'register_post_type_args', array( $this, 'wpse64458_modify_cpt_registry' ) , 10, 2 );
}

}

return $args;
}
}
}
then inherite the class with new WPSE64458_CPT_Register();
With this example I disable editor role to add new member post functionality. modify whatever you like, or you can do this others as well. but you previously mention that you already tried to follow WooCommerce, actually they also do this way,
Hope it make sense to you.
HappyCodding!
