I recommend not enabling any cache settings if you are using pages and a custom domain, as pages already have built-in cache rules.
If you want to set up caching, it is better to add a hash to the names of assets such as CSS, JS, and images:
/js/2gbnode_modules.js?h=1233
/css/simplewebpage.css?h=1233
/processed_images/catimg.6d7d16ef1617f326.webp
And add a cache rule for the assets folder; you just need to adjust it accordingly.
