Not simple but worth the effort IMO. Totally agree with your list, use FOSS when possible, Adguard Home makes for great DNS filtering, I’ve been a fan of Kagi for search, gotta pay a little but get a ton of control over your search engine.

If someone is comfortable with computers I highly recommend looking into a VPS, you can get one cheaper then cloud services and use tools like Yunohost to make getting started self hosting not hard.

Good thing I cashed out after only losing most of a couple hundred dollars 😆😭

All solved with one simple step, DON’T INSTALL THIS GARBAGE!

I have been hosting tools with Yunohost for a few years now, it is great! Fully FOSS, tons of packages available and if there isn’t an app for what you need today but you’re comfortable building from raw, the community is always stoked to have more contributions https://github.com/YunoHost-Apps/

If you’re worried about Kagi’s connections, I recommend checking out this podcast with the CEO
