Blocking Ads and Trackers
I use a NextDNS to block ads and trackers at the DNS level. I have the profile on all my devices. I also uBlock Origin as a web browser plugin. If you want more privacy you could self-host a Pi-hole server
Free VPN
I use Tailscale on my Apple TV, which allows me to access my local network when away, but also as a free VPN when abroad in countries with restrictions.
