I have used GlassWire (not affiliated) for a few years without issues.
It's also rootless so I assume it has the same restrictions, but it's been very helpful with apps like Uber, which I use seldomly, but prefer not to have their notifications shoved in my face every 30 minutes.
It's also helpful for disabling access to most of the bloatware that comes with e.g. Samsung phones and such.
Probably not blocking everything, but I feel like it's at least something.
