One thing you missed
Besides solar flares and geomagnetic storms, you missed the doozy - coronal mass ejections (CMEs). This is where a large mass of solar plasma is ejected by the Sun into space at speeds of about 2500km/s. If it hits the Earth in this day and age, it will wipe out all our power grids and electronics on the incident face. There was one a few years ago, thankfully on a side of the Sun facing away from Earth, the STEREO-A storm of July 2012. Estimates for a CME hitting Earth are about 12% probability and for between 4 to 10 years to recover, with impact costs of USD 1-2 trillion in the first year alone, as you stated. Low probability but high consequence.

Is electromagnetic hypersensitivity (EHS), characterized by sensitivity to non-ionizing electromagnetic fields at levels well below those permitted by international radiation standards, actually just the "nocebo" disease du jour or does it have a basis in science?
ESD has been around for a long time probably since shortly after the Big Bang. For most of human existence, it's made itself known by macro effects such as static cling and mildly shocking encounters with metal objects. Since the advent of semiconductors, though, protecting electronic devices against ESD damage has been a prime goal of manufacturers; failure to do so can have catastrophic consequences
What's the problem with such larger-than-life figures towards the end of their reign? Why do they so rarely ride off into the sunset in a blaze of glory and record profits?
My first job out of college was testing and debugging control loading systems on flight simulators for 747 and the "new" 767 airliners.
