Based off all the replies so far, I don't find difficulty following the feedback. Whether Canon calls their flash option "optical" wouldn't matter much even if it does work optical in a limited fashion. I tried firing my Canon speedlites with another brand, and it doesn't work. So at the moment, I'm mainly concerned learning what flashes can be optically triggered by most ANY speedlite or monolite.
Evidently, Canon 430EX ii (etc.) is does not fill those shoes. But it looks like Godox and Yongnuo can achieve what I'm after. I wish the 430EX ii's would trigger from any other speedlite flash, but they are still good units and I plan to keep them. At least I'm learning where in the "FOOD CHAIN" to use them. If I experiment with a half dozen speedlites, it may as well be the other brands anyway to keep the cost down.
If you want to mix and match lights and not worry about their communication systems not being compatible (such as Canon's proprietary slave system), just make sure the flashes you're looking at have "optical slave" as a modality for triggering. The R2 system has this in their flashes (Flashpoint R2) as well as your Flashpoint 360, etc. They will all trip from any flash pulse (including your 430EX, or your camera's on camera flash if applicable, etc).
Mean while, you can also just use a system with transceivers such as Yongnuo's RF603 system, which are very inexpensive and bullet proof as manual triggers, and simply not use anything as a slave or any optical triggers and simply use the transmitters to handle it all. Then you don't have to worry about what flash maker, what abilities it has, etc. $15 a pop usually. So they're cheap enough to get a few and solve all issues.
Just for fun, radio is just a wavelength of light, so it's optical too. We just use wording differently because its easier on our brains. But obviously wording matters as you have found out in your experiments with regards to "optical."
