- email, everybody has that, if they can't use it, well up to them to offer an alternative but anyway with DeltaChat I can get notified instantly.
- Web. Sure the app does provide some convenience but most banks do have a working website that do not need an app as usually SMS 2FA works.
- Real taxis do have phone numbers... but they also have apps and most do not required Google Services AFAIK
- OpenStreetMap and CityMapper and (I know I'm going to sound nuts) but actually road signs or asking people
- No but same, plenty of apps on F-Droid that don't require Google Services, otherwise... a .txt file? .ods spreadsheet with visual? Same on NextCloud so you can share with others even though nobody cares? (sorry)
- PinePhone, PinePhone Pro, Purism Librem, and (ahem...) Apple iPhone if you want a compromise between privacy and still convenience?
