I use a VPN and firefox and I get some extra captchas but not enough to be annoying. And you don't have to do anything more than tap the checkbox.

Meanwhile a bunch of "security" products other websites use just flat out block you if you're on a VPN. Other sites like youtube or reddit are in between where they block you unless you are logged in.

Cloudflare is the least obtrusive of the options.

No, the least obtrusive option is the one you don't even notice because it actually works (or offers a non-painful secondary flow when it doesn't).
