I cover my webcams, I have almost entirely de-Googled (since they've been attacking Invidious, I've had to resort to watching the videos on YT if they aren't on PeerTube or Floatplane or whatever), I use Linux and BSD, I am planning to switch to GrapheneOS at some point, and I try to avoid software and services from countries with problematic governments (e.g. China, Russia, USA). I am also using local software, with data sychronised via SyncThing (currently just my notes and passwords, but the list is growing).
I also use Mullvad Browser when available, and either Brave or Epiphany when it isn't.
I am still on the lookout for a decent search engine, though, as all of the ones I've used are either not as private as I thought (e.g. Ecosia, Qwant), or are broken (e.g. LibreY), or did something I disagreed with (e.g. DuckDuckGo, Brave Search), or are hostile towards VPN/Tor users (e.g. Startpage), or didn't have good enough indexes (e.g. Mojeek), or became unavailable to me (e.g. Peekier, MetaGer).
You guys just need time, I think. I'll probably be a proud Mojeek user in the future, but for now I need something a bit different. That said, I have found Mojeek to be excellent for finding smaller blogs and articles that I wouldn't otherwise have read, so it's still pretty useful even if I don't use it as my main engine.
Just fyi https://inv.nadeko.net/ somehow still works. Also there is stuff like freetube/libretube. As for search engines, I assume you have mullvad vpn, you could use mullvad Leta (don’t know how good they are right now, haven’t used them in a while). Also there is Swisscows
