I tried analyzing all outgoing traffic on my laptop for a couple days, there is a surprising amount of noise [1]. Very hard to spot anything nefarious. It's challenging to find anything meaningful without some sort of automation.

Unless it's a low traffic device, like a TV.

But in my research I didn't come across any router level software that did this in a meaningful way (with a GUI).

Maybe a startup opportunity here? +1 with network intrusion detection for home networks. I'd donate to a crowdfund for that.
