The best way to get rid oft the spy crap entirely is to get a pixel phone and flashing GrapheneOS (de-googled Android). Dw, it's not that hard to do, there's a good manual. Sure you need to find alternatives to google apps, but so far I could get replacement apps for almost everything FOSS from F-Droid store. Some apps cry for play services from time to time, but only a few of them won't work at all without them. Most of the time it can be ignored. You are able to install a defused sandboxed version if something really needs it tho. If you need an app from play store you can use Aurora Store (Foss play store client). Even E-SIM works without problems. And the best is 7 years guaranteed updates starting with the phone release. The a series is quite cheap (got Pixel 8a for ~460€). I can only recommend this setup.
