What worked for me was disabling the feature of keeping the TCP connections alive. No idea if it's covered by 'networkoversleep', but this is as deep as I've went, considering I've then received a warning that "Find my Mac" will stop working after this toggle.

yep, I did the same. So, last time I dug into it, I found a separate issue where it would darkwake to do things like check in with find my mac, and then an app that had an idle power assertion would prevent the darkwake from fully shutting down again. That's separate from it getting into a weird loop of waking and sleeping though.
