I'm sorry but no, the original video does clarify some important things that people misunderstand about transmission of electricity, but then it piles on a bunch of other really unclear information with no explanation. It answers a question with about 8 other questions and then offers no help in understanding any of them.

You can't just say "there's electricity at the light bulb nearly immediately! (oh by the way it's not very much electricity but I'm not going to explain why or even how much less, and it's probably not even enough to turn on an LED but I'm not even going to mention that)" and then get pissy when people are like "???!??!?!" It's pretty blatantly deliberately misleading and confusing in order to stir up exactly this controversy.

Especially since the effects he's describing are probably (as mentioned in this video) because of capacitance, and are completely dependent on the 1m distance between the wires across the entire span, a constraint he mentions basically once and then never again, and never says explicitly that it's related to the effect.

This video and electroboom's videos are far more educational, and more importantly don't leave you hanging with a bunch of new questions with no resources provided to answer them.

YES. This is my biggest gripe with the video. A better shape of wires would be a pair of tangent circles, each one with a circumference of 1 light-second, and a 1-meter section removed at the tangent point. (Hope I'm describing it right. Basically but only the switch and the light bulb 1 meter apart, but get the wires as far apart from each other as possible)

Now would that eliminate capacitance? Or largely so? What amount of current would begin flowing across the bulb at t₀?

After seeing that video and all the reactions, I know more—but not from the original video. My mental model of electricity is still that it "flows along wires", but I now can somewhat separate the movement of charged particles from the energy flux those moving charges propagate. I think.
