I just don’t use any sites like that. If a site is using something other than Turnstile from Cloudflare, then I refuse to use it. I haven’t really experienced any inconvenience myself with this policy, but obviously I don’t depend on any sites that require recaptcha.

But you can allow/block any elements per site, or globally, which makes it trivial to block all unwanted scripts except on specific sites. So there is nothing preventing you from only exposing yourself to Google on the few sites you use that need those scripts.
