Use an alternative DNS server, Firefox/Brave/Ungoogled Chromium, uBlock Origin, and disable JavaScript everywhere you can possibly help it. As far as reclaiming some privacy from routine surveillance, this is probably better advice than "Pay Unknown Company X $9/mo to maybe be slightly better than your ISP in terms of privacy".
