/ Generac Running, But No Power in House #41

A whole house surge protector should really help. As unclean as the switch over may be, I am a little bit skeptical that the voltage would be extreme enough to kill your appliances. Generators by design don't much over 240 by design, unless they fail. I would put my money on the lightning storm for that.
On the whole house surge protector, I would try to make sure that you set up the wiring to be covered by both grid power and generator power. The general advice is to put the surge protector as close to the meter as possible, but that is likely to isolate it if the transfer switch for the generator kicks in, so you might want a second one at the generator. I would file it under cheap insurance.
If you are having power quality issues, there are ferrorresonant/autotransformers that can "smooth" the power, but they are pricey.
I saw someone who did the math for his power issue and built a homemade toroid for power smoothing;

That is a single conductor, so you need two for 240=2*120. But, no, I am not seriously suggesting that you make one.
All the best,
Based on what I've learned on this thread, I was expecting a surge protector to be installed on the circuit panel in my house and barn, and I thought that this approach would hopefully protect my appliances, regardless of whether the surge originated in the outside power line or the generator. Is that accurate?
I feel confident that most of my current issues (no pun intended) are from the recent lightning storm, because we saw the immediate result. I've now had two cases where an appliance failed immediately after a manual switchover to generator power, with no bad weather in the area.
I also think that my ethernet line between the house and barn is a major culprit, and I'm hoping that an ethernet surge protector on both ends will help. I've now had two cases where a storm has damaged the network switches on both ends of that line, a laptop connected to one switch, and a network camera connected to the other.
I have already replaced the inexpensive network switches again, but I'm holding off on the expensive items, until I have better protection.
