When you have a multi site shop and you have a product type which doesn't have urls for the primary site (or where your CP lives) they won't show up when you want to link to them inside a Redactor field. As only the current site is checked https://github.com/craftcms/commerce/blob/develop/src/Plugin.php#L397
This should look for the site dropdown inside Redactor itself.
Now you are forced to give them a url on the primary site to be able to link
