I’m using Qwant browser which uses Qwant search engine. Both the browser and the search engine are actually quite decent, and I think it’s a French project
Have you checked tailscale? a one click wireguard, free for quite a lot of devices.
there is a project to selfhost the control server https://headscale.net/
As said I migrated to use their ios browser: https://apps.apple.com/nl/app/qwant-private-search/id924470452?l=en-GB
if you want to stick to safari there seems to be also this https://apps.apple.com/nl/app/qwant-for-safari/id1645050159?l=en-GB but i haven’t tried that myself
i suggest you give it a try to the browser, i’m quite happy with it
