Increase capacitor voltage rating by using multiple capacitors?
You can put capacitors in series, but that rarely works out better than getting the right cap in the first place. As Steven said, two of the same caps in series have double the voltage rating but half the capacitance. You also have to be careful that the DC level of the node between the caps is at about 1/2 the voltage.

How to choose capacitor voltage rating for ESD protection?
$color{red}{boxed{^1}}$ 195 volts is a little high due to the liberty I took when reducing the 50 MΩ resistor to 100 kΩ. I took this liberty to speed up the 150 pF charge time so that the sim result was more easily viewable. In reality, with basic charge redistribution from the 150 pF capacitor to the 10 nF capacitor, the peak voltage would …

For medium and high voltage applications, low loss aluminum electrolytic capacitors are required. Low ESR capacitors have fewer power losses and internal heating problems as compared to high ESR capacitors. Apart from lowering performance, high ESR values reduce the life of an aluminum electrolytic capacitor. In addition, a low …

What are some reasons to connect capacitors in series?
I have only seen it done to increase voltage. On some power supply front-ends (AC/DC conversion) with a voltage doubler the capacitors are in parallel at low voltage and in series at high voltage. This works out well since for a constant power out the current is double at the lower voltage. As you mention balancing resistors are required.
