I dug further into code for your question regarding query caching. Though the flag is enabled in hibernate configuration for all modules, query cache is only enabled programatically (query.setCacheable(true)) for CMS. Following your previous response and as per http://wiki.jboss.org/auth/wiki/JBossCacheHibernate, does it mean that INVALIDATION_SYNC would be worth trying when CMS is not used?
