A lot of paranoia on this community :(
There's a few sign in checks (The variety makes me think Disqus or something similar.), a couple of keep alives, your phone registering for Wi-Fi calling, Fallback DNS requests, a couple of CDN requests which I would get is likely update checks and finally YouTube content for NewPipe. I think I'm seeing five tracking cookies based on the rest of your apps here, probably being sent "Do Not Track" requests.
