So after checking out a lot of options, I decided to go with a surround gate. For now it is in my bedroom (no shared wall), but maybe downstairs might be better.
I made her a new bed.
I will keep her crate in there to start, as that is the only thing she has known for 6 months. I will move it out once she gets used to the new space.
With over 4x the space, I think she is going to like it.
