Congrats! And way to go foradopting! Rabbit personalities can be very different withdifferent individuals, even in the same breed. Same goes forgender, although I have heard that sometimes males are moreaffectionate. That doesn't mean that females aren'tnoserub-begging cuddlebuns though.
Spay/neuter helps a lotbecause they're not ashormonal and frustrated.Netherland dwarfs do have a reputation for being energetic.But the majority of rabbits hate being held anyway. Ittriggers a fear instinct for them, because they are prey animals.
If you want to adopt a rabbit that matches your personality, talk tothe shelter staff and play with a number of different rabbits there tosee what they're like. And don't limit yourself to breedunless it's something you can't take care of well, like an angora thatneeds lots of grooming or a flemish giant that needs more space thanyou have. There's nothing wrong with wanting a specific breedlike Netherland dwarf, but it does limit your options when you'relooking for a rabbit whose personality matches yours.
As for the cage, you could do better. That's actually muchsmaller than the picture looks, and Ifindthosesmall doors annoying. Plus it'sbest if the rabbit can hop in and out of his cage when he's outplaying, so you'd need to build a ramp or steps. Have youlooked into dog crates or NIC cages? I made a 56 inch by 28inch NIC condo with a 14x56 inch shelf for about $60, and I usedrelatively expensive stuff for the floor. It could have beendone for less money. Or you could get a big dog crate for thesame price as that cage and put in a shelf yourself. Dogexercise pens can also work well if you put down something for a floorand your bunny can't jump out.
