What are some reliable alternatives for both iOS and Android? I'm unsure how are Apple Maps, but they were hideous a while back for Eastern Europe at least.

HERE WeGo[0] works remarkably well here in the north of Africa, much better than google maps or TomTom.

Watch out, Here Maps has the Facebook SDK malware embedded in it that will call home to Zuck on every app launch (at least) and send a device fingerprint and persistent identifier.

Very unfortunate, since HERE maps allows offline maps.

We need a public registry of apps that embed tracking SDKs.

And iOS needs an outbound firewall, now that it is shipping an App Privacy Report.

This can already easily be added through third-party apps. Would a system-wide firewall be a worthwhile improvement? I suppose it would help to have it enabled by default for users who wouldn’t install a tracker firewall app afterwards.

Is there an iOS 3rd-party app which can provide on-device outbound firewalling across all apps?

Yes, AdGuard seems to do so and IIRC also has customizable block lists. The default includes Safari-only blocking but it is able to add a device-wide filter using Apple's API for VPNs. It seems to identify the various trackers used by the social media apps on my device, for instance.
