Almost every multiple LED 12v strip I've ever used has the LEDs grouped in threes wired in series, likewise 24v strips are divided in to groups of six. I don't entirely understand the electrical science behind it but I think it's something like the voltage experienced by each LED is within tolerances even though the overall input voltage isn't, and if you were to try to cut the strip within a group it'd blow up that group quickly.
Those strips should use slightly less power for a given number and brightness of LEDs than their lower voltage counterparts because the higher voltage is losing less power to resistance over a given distance, same as high voltage transmission lines.

Pretty much every WS2811 controller board is 5v, because there is only one manufacturer and that's all they make. The strips with 12v have a resistor on each one because people like to use 12v since you can power more lights before you have to inject more power.
