If any Chrome users are reading this: You can just use Helium which includes uBlock Origin (not lite) and is based on Chromium.

You can install Aurora Store and use that instead of Play Store. Though be aware that disabling/removing Play Store may cause issues with some apps that require Google Play Services for some reason and those apps don’t have to be completely proprietary for this requirement (Stoat’s mobile app doesn’t launch at all without Play Store for example).

I would also recommend disabling background connections and running in the background for proprietary apps you install. I’m not sure how you can do this on Samsung but this is how I do it on Xiaomi:
Running in the background: App info -> Power -> Select “Restrict background apps”
Background connections: App info -> Network access -> Disable “Background data”
