I think if you up your bunny-proofing you will both be happier, both before and after his neuter. There are lots of good tips on this site, if you go to the “Bunny Info” tab at the top, there is a section on bunny-proofing.
You can use an exercise pen or cube grids zip-tied together to block him from jumping on the bed as well. Cube grids might also help you reinforce his crate so he can’t fit through the bars.
Cords should be kept out of reach and protected. You can use more cube grids or position them strategically so they are behind furniture.
I do agree that Apple cords especially seem to be the forbidden fruit to bunnies LOL. I think because they are thin and soft? The instinct to chew cords comes from their resemblance to a plant stem or piece of grass.
It can help to hang up a towel or blanket over the part of the pen that he is rattling as well (so if you put up something around you bed and he’s messing with it, that might help).
