But they all seem to offer only a web page for access, no proxy
configuration data for your web browser.

Perhaps you are asking for the impossible, because there is no
business model for what you are looking for. Proxies need a lot of
bandwith and have to obey to law, both is expensive.

Offering a proxy over a web page makes ads possible. And selling VPN
services is a business, too. Offering a free web proxy with
configuration data makes no sense - who should pay for it?
