There's a huge amount you can learn from analytics.

You can both self-host or use their managed service. They are absolutely competitive with Google Analytics.
You are selling out the privacy of your users so you can save ten bucks on analytics.
Countly - a little richer, e.g. geo view
Matomo - the most feature rich, closest to GA (haven't used)
(I'm blocking all of those, but requesting them could lead to additional requests.)
(I don't block the third-party for Cloudfront, where you seem to host Wordpress.)
(The third-party request purporting to be for privacy is arguably counterproductive.)
(I thought I saw a Google/Doubleclick one earlier this morning, but don't see it right now, and I could've be mistaken.)
Towards your goals of ethical, it might make sense to strip out all your third-parties (except Cloudfront, for now), and if you really have to add anything else, self-host it. Otherwise, you're leaking cross-site tracking&profiling information about your users, generally without their awareness, which I'm sure is not what you intend.
Good luck with your effort.
