One of my favorites is Whoogle, a simple Google search proxy. It accepts search requests and forwards them to Google anonymously, then strips out the AMP links and tracking. There's even an option for it to use Tor so your IP address changes frequently.
I used both, I ended up settling on searxng because Whoogle seemed to be unable to retain my settings. Might be something with my cookie configuration, but searxng has no problem remembering my preferences. If that is not a problem for you then they are comparable; Whoogle is pretty simple to get going and works well, searxng is slightly more complicated to set up (but not that much with docker) but has a ton more features.
Does your server have to be accessible from the internet or is it enough that it can go out to make the request? Just asking because I am keeping my setup in our intranet, no access from outside my home.
