What to do with new Android device?

New tablet. I didn't sign in and want to maybe remove Google Play Services entirely (and degoogle and de-Samsung it), but unsure of how, if I should, and if it would even last due to OTA updates.

Have installed F-Droid and Bromite.

What else should I do? Looking through F-Droid there's Adaway, Wireguard, dns stuff, etc. My old tablet was Kitkat so I'm not used to modern Android's options.
