The real secret of an effective captcha-like system is to identify/collect lots of data, identify suspicious patterns, validate them (checking what kind of data exposes a bot-like system) and then use this for serving dynamic challenges based on a couple of information.

Example: if the system identifies the user as a bot, it tries to give a less performant solution in terms of PoW.

Maybe somebody could explain me why your comment is in different contrast of grey?

I think somebody might have flagged your comment, but it is a real fact.

This is one of the reasons why people say cloudflare owns the majority of internet but I think I am okay with that since cloudflare is pretty chill. And they provide the best services but still it just shows that the internet isn't that decentralized.

But google captcha is literally tracking you IIRC, I would personally prefer hcaptcha if you want centralized solution or anubis if you want to self host (I Prefer anubis I guess)
