I don't necessarily mean financial risk (though tbh, even the golden parachutes you cite are often a drop in the bucket compared to the market cap of these companies), but there's a lot of legal risk involved: think testifying to Congress, embroilments with the FTC/FCC, etc., dealing with a board of directors, navigating potential hostile takeovers or activist investors, etc. My point is that it's just a different ball game and being a CEO of a public company simply isn't the same thing as being an accountant that works 9-5.

I personally have significantly more of a problem with Congress having no term limits and being able to trade on the very market they're regulating.
