If you want something sophisticated and like to tinker, set up a Wireguard VPN and an adblocking DNS server on your home router. Funnel all your iPhone traffic over your home-rolled VPN with the flip of a switch (VPN on/off in iPhone settings), and let your router serve you ad-free traffic via DNS filtering. This has the benefit of stopping ads in most apps, not just Safari. Combine this with a Safari-specific add-on for an extra layer of protection.
