Personally, I don't see fusion as relevant on a time scale that will impact the climate crisis in any significant way, but it could be a major asset in taking us from net zero emissions to preindustrial carbon levels. It could also simply just be a way to achieve cheap and abundant energy in general, irrespective of climate issues.

But as you said, of course it's an open question whether fusion will actually be more economical at scale. It could conceivably turn out to be a day late and a dollar short on Earth, and more relevant elsewhere.

I'm keeping my eye on Helion (the one Sam Altman invested in). Seems they're making some pretty big claims, and have already entered into contracts to deliver to customers by 2030 or face financial penalties. Could still be vaporware, but they seem to think they have something.

Would there be any obligation to pay out financial penalties if the company declares bankruptcy?

Obviously not. Those customers would have to line up as unsecured creditors, so the "penalties" are only theoretical and exist mainly for PR purposes.
