Have you considered pi-hole[0], NextDNS[1], or AdGuard[2]?
To be fair, I don't think you can install certificates on a Chromecast for example, so it might not be practically feasible for all devices, but a blanket "SSL makes that impossible" is not correct.
That’s news to me. Can you expand on this ? I always assumed if an API Endpoint for example is served on TLS it’s secure till the termination. No ?

Cert pinning isn't used by browsers in general.
