Temperament isn’t really breed specific, since rabbits aren’t really bred for specific temperaments (other than being generally pleasant) the way dogs are. The only real generalization that I think holds true is that bigger breeds tend to be calmer than smaller breeds.
If you’re really concerned with personality, I would absolutely get an adult or adolescent bunny. I got one of mine (a holland) at 8 weeks old, thinking I could socialize him, and he wanted none of it. Don’t get me wrong, he’s a great rabbit who is very laid back, but he does not like to be touched. So he’ll happily run over to see me and other new people, but reach out a hand and he hops just out of reach unless you have a treat. There was really no way to tell that about him when he was a baby, and I worked very hard to socialize him, so I think personality has a very strong genetic component.
I got my female (a mini lop) as a 3 year old, from her previous owner, and she is a very sweet rabbit who loves attention and pets.
Males may be nicer, but I think that’s generally only true about unfixed bunnies – unspayed females can be territorial and mean, more so than males, but spaying usually fixes that. I think females can tend to be more opinionated and bossy sometimes, but that doesn’t mean they can’t also be sweet and enjoy snuggles (my girl is like that). If you get an older rabbit, finding one with the personality you like is more important than gender.
Definitely post pictures once you get your bunny! I love hollands.
