IndexDB and Cache cannot be cleaned on leave. Rules can only define that a domain is cleaned at a different time but you cannot make different clean rules for a domain, like: For this domain, I don't want cookies to be cleaned at all but I still want everything else to be cleaned according to global rules. Thus you can also only choose to clean all cookies or no cookies, no way to make exceptions for single cookies only. Cookie AutoDelete can do all this and has none of the restrictions mentioned.
