Very large and expensive textbooks have been written on the subject of power protection and grounding.
A good (at the no-mathematics level), cheap but somewhat older book on power protection is Protection of Electronic Circuits from Overvoltages, Ronald B Standler, published by Dove. Focused more on whole-device protection rather than individual-IC protection though.
NB. Capacitors on supply pins of ICs are usually more for 1. mitigating noise emission from the IC onto the power rails, affecting other circuit components; 2. stabilising the power supply to the IC (and so its operational parameters) while it deals with signal transients.
If you are worried about an individual IC getting voltage spikes on its power supply pin(s), then you're probably doing it wrong. If not, use TVSes (transient voltage suppressors).
