Computer browser: Brave + uBlock, LocalCDN, Privacy Badger, SponsorBlock (+ Invidious, Redlib, Nitter, etc, when it makes sense)
Phone: Hyperweb (for redirections to alternative frontends) + AdGuard Pro + ControlD DNS-over-HTTPS
Router: ControlD DNS-over-HTTPS
If you're using OpenWRT, check out AdGuard Home. But keep in mind that DNS blocking solutions aren't going to be as effective as tools like uBlock that review the DOM and apply styling filters. Both would work hand-in-hand.
