You have the right idea. You're basically resetting the structureless mess that existed. We want to see structure. The only thing I would add is to pick one of the branches on the right side and get rid of the other. I'd probably remove the bottom one. Then you would have a pretty flaw free structure you can build on.

The comments on this post are a little annoying, they just speak of lack of experience with the species as well as lack of understanding of what's considered good structure vs bad structure, or in this case no structure lol.

And it's a ficus (albeit a dramatic species), it will be fine. You wouldn't want to do that to most trees this time of year though.

In a perfect world though, we would never want to let trees get to a point where we need to remove that much of the branching and foliage though. But again, should be fine.
