Netflix Party (browser extension): Syncs netflix
SyncLounge (webapp): Syncs plex
twoseven.xyz: Create a room and play Youtube, Netflix, Prime Videos, Hulu, or really any <video> on any website with the extension
Tuturu.tv / Caracal.club: Gives you a VM in the cloud where you can play any video and watch together. Good when you have only a single netflix/hbo account or whatever. You're guaranteed to have a single view and can share control.
SyncPlay: An plugin for VLC/MPC that syncs local files
There are many more, andchill.tv for Youtube, Kast, and so on. Zoom is probably the last solution i'd use for this.

I can understand wanting to avoid bad press given the current state of things, but even still I'm shocked that Netflix and especially Disney haven't hit these with C&Ds for trademark use given the obvious potential for confusion.
If it was "Watch Together" or something, it would immediately clue me in that there was something else I was going to need to install or sign up for in order to make it work.
Regarding discoverability, can't Chrome extensions register themselves to handle custom schemas? If Netflix Party gave you a party://netflix/movie-id/session-id URL, then it would fail to resolve on a machine without the plugin installed, while still not requiring any centralized infrastructure.
I'm not sure if there's a way to create a platform to play any game through Zoom, but if you have a Google Form with game requests, I'm sure you can very quickly scale up your offerings with confidence.
