After a power outage, some electronics refuse to turn back on unless I unplug the power brick completely on the electronic side. Why does this happen?

It’s hard to tell without a circuitry layout, but my best guess is that there’s probably capacitors in the power brick acting as an electrical filtration for the motors to make them operate smoothly and reliably.

The capacitors are probably discharging some electricity that are keeping some circuit protective device alive. Unplugging the power brick is probably the only true way to completely remove electricity from the unit.

why do half of plug designs take up multiple spaces on a power strip?

So AC devices typically are just a low profile plug and wire. Since they natively run on your houses power source there’s not much going on other than internal fusing which doesn’t really take up that much space.

Most electronics, however, are DC, a lot of electronics are being made as dual voltage. Regardless, this means that the device needs some kind of voltage converter. Manufacturers can either build the converters into the unit itself, or they can build the converter into the plug circuitry and save space on the item the consumer is handling. Consumers have vastly chosen to deal with bulky wires and slim devices.

It’s just a theory based off of my own experience, but if that’s the issue, it kinda depends on how large the capacitors are and what kind of capacity they’re capable of holding.

If it is the issue, I’d expect it to take like 5 minutes for it to discharge completely, but that’s just a guess. If everything is already out of its usual place, you could probably test it if you’re curious enough.
