F1 cars are using energy recovery systems for heat from the turbo charger, and kinetic energy from braking. All thats 3-phase AC, then it can be stored in batteries after converting to DC, and converted back to AC again and fed back later. Too bad these era engines sound awful, they sure are impressive.

Most all the electronics are at their thermal limits from engine heat and lack of cooling.
I'd ask a bunch of questions about the electronics on board them, it's hard to find videos with actual technical chat

Well the teams do keep the latest technology a secret to avoid rival teams seeing it.
But overall id expect it to be pretty similar to your usual brushless motor controllers you find in all sorts of RC models and electric vehicles. The power electronics for running a brushless motor or asynchronous 3 phase motor are the same, just the control algorithms are a bit different.
But yeah no doubt those are some serious power electronics in there to handle these sort powers while also being as light and efficient as possible. The engines run at the brink of tearing themselves apart, so id expect those poor power transistors in there to also be running on the edge of blowing up.
