I recently de-googled my phone by installed Lineage for MicroG. I want to find a good FOSS firewall app to use. I don’t want a firewall app that just uses a VPN as its method of running.

On a test device, I’ve been using AFWall+, however that hasn’t been updated in 2 years (At least on F-Droid). It works great, but I’m not sure if there is something more up-to-date.
