Hard agree, and as far as I know (but I would be very happy to be proved wrong) there is no setting on Google Analytics which allows you to rein in the privacy controls so that only your organisation gets that analytics data, Google gets the anonymised data regardless.

Matomo analytics is the one we have started using on our own (Delib owned, not customer) sites as you have control over the whole thing so you can lock down the privacy settings to only collect the bare minimum, anonymous data and you own 100% of it: https://matomo.org/100-data-ownership/ and https://matomo.org/privacy/

Even then, I’d only want us to use analytics if we’re actually doing something with the insights from that data to improve what we provide on our sites. If people opt-out (as they can) and that data is not longer useful because it isn’t the whole picture, then I’d vote for no analytics.
