The only privacy-friendly CAPTCHA is a self-hosted one.

The only user-friendly kind is none at all.

Depending on the web site, an alternative bot-filtering strategy might make sense, such as:

Allowing signup without a CAPTCHA, but requiring one before the first post/upload is allowed.
Allowing signup without a CAPTCHA, but deleting accounts that behave like bots.
Allowing signup without a CAPTCHA, but deleting accounts that don't purchase something.
Allowing login without a CAPTCHA, but restricting retry rates and/or temporarily locking accounts after 10+ failures.

Cloudflare's Turnstile has an invisible mode that you're probably using in a lot of places and aren't aware of it. It provides an invisible challenge to the browser and requires no interaction. I would say no input require in quite user-friendly.

Yes, the Honeypot system, an invisible part, only visible for bots, they use it and get blocked. easy.

I would argue that's not a CAPTCHA at all, since it's not a Turing test, but rather a browser inspection.

In any case, Cloudflare services like these are not remotely privacy-friendly.
