- Reduce default cache constant that was removed in #9841 (removed as currency wasn't included in cache key, now is added via this plugin https://github.com/VortexCommerce/magento2/blob/23d76ed074d7d5e465cbed782a2831abe192de96/app/code/Magento/Catalog/Block/Category/Plugin/PriceBoxTags.php#L68)

- Increase default cache time to 1 day (86400) this is more that acceptable as the cache key includes the current date so will not load for a new day which could have a new price rule, special price etc...
