Yeah, sounds like she’s ready! 
We had a weird experience with Oscar’s neuter. It worked wonders for his litter box habits, he was 100%, literally from the day he got fixed, it was quite amazing. After a few weeks however, his behavior changed for the worse. He became quite aggressive, especially around food and in his cage. Now I’m not sure if this would have happened no matter what, or if his lovey dovey hormonal feelings were overpowering this aggression before his neuter. So I’m not blaming the neuter for this, there is no way that I wouldn’t have had it done, so don’t let this discourage you. I’m the first to advice anyone to have their bunny fixed and of course with a female it’s even more important than with a male. With that being said, after putting a lot of work into our relationship, Oscar has made huge strides and now there isn’t much aggression left, if any. It’s mostly rabbitude.
With your Fuji it sounds like her aggression is very much hormone related, so she should go back to her friendlier self after her spay.
