This is a great write-up @PaulaFairphone! Very much like your list.
I think I may add a Navigation section to my awesome-humane-tech list, and add OSM and StreetComplete (though I don’t want to duplicate existing ‘AlternativeToGoogle’-like lists too much). Didn’t use Mozilla Location Services before, because of some privacy concerns (haven’t checked thoroughly).
Blocking based on hosts file is nice, but not for everyone, if it requires ‘rooting’ the phone (voids warranty). My awesome list has a Trackers section with some more options. Blokada for Android seems a nice one in this regard, but I’m not using it yet.
Edit: I added a number of these resources to List of awesome open-source Humane Tech projects, thank you @PaulaFairphone
