Hello and welcome to the forum.

My first thought is that given you don’t want to be brushing more than twice a week, is to instantly rule out a cashmere lop. Long haired breeds need very regular brushing, preferably daily just to keep them from getting tangled. Rabbits shed, a LOT, regardless of breed (though the rex breeds may have less fur floating around because they only have the short undercoat). Sometimes when my rabbits are shedding, I brush them daily to prevent them ingesting so much fur. Rabbits shed very heavily multiple times a year, pretty much regardless of breed.

In terms of personality, most rabbits do not like to be held and cuddled. If that’s what you are looking for, your best bet is to go to a rescue to meet adult rabbits whose personality is already well formed and try to see if one there is more of a cuddler. My boy, Apollo, absolutely loves attention and loves being petted, but he will not sit on laps or be held. None of my rabbits have ever enjoyed being held, they will tolerate it a short time, but that’s it. You’re sure you don’t want a cat?

From the breeds you mentioned, I believe Holland Lops tend to be more laidback, Netherland Dwarfs can be high strung (though not all are), more than other breeds I think they are not cuddlers, though of course it’s a generalisation and there are exceptions. I’m not sure on Dwarf Hotots.

There are stereotypes, but not every individual will fit the bill. Hollands are said to be more laid back and Nethies are said to be hyper and spunky. My Holland is pretty laid back, but he also has his weird little quirks. I have a a Jersey wooly, which has Nethie in the bloodline. He isn’t hyper necessarily, but he has some serious bunitude. He can turn on a dime when it comes to his moods. He can be super sweet one minute and a little pill the next.
