Safari 14 does not seem to work with American Express or several other important sites. It says the pages needs to reload then give a blank page with an error.

I just tried logging into my Amex account. No issue. Try creating a new clean user account. Login to the new user and see if you have the same issue using Safari. If you don't, from your current user account try this:
Safari→Preferences→Advanced, enable Show Develop menu in menubar. Select Safari→Develop→Empty Caches.
Exit Safari.
In Finder, browse to your user account Library→Containers, move all the com.apple.Safari* folders to the Trash and empty the Trash.
