How do I choose not to use Google properties, including their ad services, analytics, captcha, maps, etc? Is there at least a comprehensive list of their domains, if I choose to block it all (despite that rendering half the web unusable)?
Blocking third parties with a tool like uMatrix will get you some of the way. Then you can generally avoid their products and block them at the top level manually, although it might be hard to avoid visiting websites that use Google Cloud, e-mailing people that use Gmail, or using software maintained by Google.
Sorry, I wasn't specific enough. The poster I was replying to was commenting on their browser and I was expanding that to mean their browser and other applications.
Blocking all access to all Google services could be an uncompletable task, unless you start from blocking everything and using a white-list approach only which it unlikely to be practical (on top of creating the whitelist you'd have to monitor it and react when they or one of their related entities buy out or otherwise co-opt services you might have whitelisted in the past.
There are fairly comprehensive (though given the volunteer effort involved I'm sure they aren't 100%) lists available, but I don't know of one specific to Google so you would end up blocking other similar services unless you add your own filter to the filter list before using it.

I doubt it would make nearly that much unusable. The only one of their services that blocking would stop you using other things is recapcha and I dare say anything "hidden" behind that is also available elsewhere. Blocking analytics isn't going to affect you as a user, maps blocks itself a lot ATM anyway ("this site is configured incorrectly" messages where a map should be because the rules for inlining maps have changed (or their enforcement has) and people haven't updated their pages to reflect the policy change at Google), etc.
