The system launcher on my phone has a data usage that is non-zero. I've already disabled background data for it.

I use Lawnchair2, but haven't tried to disable/uninstall the system launcher because I've read somewhere that it affects gesture navigation(Is it actually so?)

I know that apps like Netguard can help, but is there a more direct solution, other than rooting?

Are there any other adb commands that are useful, hopefully that are not too dangerous?

I've recently found
adb shell pm trim-caches 99999M
Clears all/most app cache, without having to install some cache clear or use Gfiles. I don't really use it often.

Along with this, does anyone know way to troubleshoot gmail not being able to download attachments on mobile data? I've not disabled background data for that.
Or should I make a separate post on it. Or would it be too tech-supporty?

The best way to achieve this is by creating an account on NextDNS, then setting your phone to use the NextDNS DNS. On the web dashboard, look at the logs and blacklist anything from Google, Google Play, or anything else you don't want. This not only works but also gives you more control over everything your phone is doing in the background, regardless of whether you're using Wi-Fi or a mobile network.

How secure/private is NextDNS?

It suffices for me if you don't enable logs; there are no logs... and if you enable them, you can choose the country where the logs are saved and for how long.
