This is a great topic, that's right up my street.
The biggest change that I made to my home privacy / security is deploying PiHole on the local network. The sheer amount of tracking and nasty ad / malware sites out there is astonishing. About 15% of all my web traffic at home is blocked at the DNS level. All of that crappy MIcrosoft Telemetary just gets stopped dead. Samsung also trys to ingest a lot of data from my TV and Washing machine, but PiHole stops most if not all of that.
When out and about on the Android phone / tablet, I've switched to FireFox and Ublock origin.
