Yep, all those franchises and that's not forgetting Ocean's Eight too. If that's successful it may also spawn sequels, especially if they're planning a trilogy like the original Ocean's trilogy.

I would agree with Artanis, although to be honest, Cate has enough on her plate when it comes to blockbusters. She has been in Indiana Jones Universe, Disney Universe, LOTR universe, she is expected to play a big role in MCU, she is also in "How to train a dragon" franchise. I mean, that's a lot for one actress.
That said, Cate has that look that I always imagined would work for Narcissa Malfoy in Harry Potter franchise, or some Targaryen in GoT/ASOIAF Universe. She could be an admirable choice to replace the late Carrie Fisher, if, of course, that is needed (we don't know if Leia will die in Episode VIII). I would definitely like to see her in something new and original, but it seems Hollywood gave up on those movies.
She can be a great hero and anti-hero. It really all depends on the role.

Uh, none of them? She's has joined the MCU as a villain and that's enough big franchises for me for the time being. She's in Thor: Ragnarok and if the rumours are true (about her character Hela being composited with Marvel's Mistress Death character), she may also play a key role in Avengers: Infinity War and it's sequel. If true, that's three movies to look forward to in the next 2-3 years.
Although, I guess I wouldn't
object
if she was asked to play a role in a future Star Wars movie. Why does it have to be a villain role though? If Cate was to ever play a role in the Star Wars universe, it would definitely be Duchess Satine Kryze (

) from the Clone Wars who's character design was actually
based
on Cate. See how much she looks like her?
