I don't know about hCaptcha, I tried it out when testing stuff for a websites checkout flow (had card testing spam issues), and they are about the most difficult to solve captchas I've ever done.

I guess there's a low friction mode only available on the $139/mo plan.

I think Google stopped using such data long time ago. They have been showing hydrants, buses, crosswalks for ages. It's a solved problem to detect them.

Maybe over a decade ago. As it stands now, it's just a surveillance apparatus.

You could probably make a decent bot resistant captcha by just asking the user to type a slur

Coincidentally today, I have formed a weird theory about reCaptcha. I created a fake facebook account recently. And every time I try to login, I'm getting verify you are human screen that is Google's recaptcha. And I was solving recaptcha for 8-9 times on some occasions. I think the number of times I have to submit in one session went up after couple of days of Facebook usage. My theory is that, Facebook tags many accounts to be fake internally and instead of banning, they use these accounts for data farming including collecting data through Google's recaptcha (but incentive is not aligned as it would help it's competitor unless there is some payback model). This is anecdotal and 99% I'm wrong. But if I'm on the other side with the incentive to use data, it is definitely one I would try to capitalize on.

Got second hand anxiety the other day seeing someone logging into their fb account (I guess with a chrome private window?) and they had to solve like 3 round of reCAPTCHAs to finally be able to... get into a fb login page over again, do another 3 or so reCAPTCHAs and finally get into their fb. I don't think they were doing them wrong
