Why storm a courthouse when you can just lay siege to the city? Cut off communication, power, transportation and water. They'll sort themselves out in no-time. People handle blackouts and lack of food & water quite well in urban centers.

🔥 FIRE & FURY 💥

I'm personally aware that substations are insanely flammable. I'm talking the ones that govern inbound long-distance transmission lines. We lost one that would have crippled our area if we didn't have the largest nuclear generation capacity in the US. Without it tho, we couldn't sell excess power to CA because all of our northern import feeds were down for over a month (we'd import cheap power and export surplus Nuclear for profit to CA) as the replacement parts were more than 1500 miles away and could only move with a special road-convoy at speeds less than 40mph.
Lose a handfull of those around any area - and that area goes dark and stays dark for good. You can't move the replacement parts into a warzone, and they're too big and heavy to airlift (otherwise ours would have been too - it was near an airbase - so I'm sure they considered it). They were even too big for rail.
