Privacy Badger by EFF should do the trick. On top of that I can recommend Firefox + uMatrix. If you want DNS-based, Pi-Hole indeed. If you want hosts based you're going to have to modify that manually (AFAIK, there are probably managers which auto update it for your OS). DNS-based is going to be network-wide, including Android TV or your wife's smartphone or... you get the idea. I got my DNS server available via WireGuard VPN. It also does DNS over TLS which adds security. Put Google in its own Firefox Container via Google Container extension. You still need some other measures to avoid tracking and fingerprinting. Using these will increase the amount of capcha's you're going to have to solve. I can think of e.g. CanvasBlocker, and setting privacy.resistFingerprinting to true. There's also a Firefox extension which removes UTM from URLs. That would be Tracking Token Stripper. Not sure about avoiding AMP.
