I think this assessment is very apt, I've long wanted to get the chops to visualize all the action taking place on my network access. It's all so hidden and under the hood, it would be very revealing for a YouTuber to do a walkthrough to show how leaky apps and websites are and what sort of payloads are coming off their devices to remote targets.

You should look for tutorials on Wireshark or better yet get a Pi-hole and block ads over your entire network while you get trustworthy stats on where your traffic is going. That's probably the easier and more useful option. Casual packet inspection used to be much easier. Common traffic like HTTP, DNS, or SMTP are increasingly encrypted, but it used to be that you'd see everything pass over the wire plainly. A lot of the data companies send home is encrypted too so you might be able to identify which apps or programs are generating the most traffic or sending it to same shady destinations, but don't expect to see what data they are collecting from watching the network.
