Thanks for the extra photos we can now see a bit more about the trunk and branches.
The good bends down low and the straight top are more clear. I'm sure that's one of the reasons you are not satisfied with the tree. Unfortunately, dealing with that is not as straightforward as it sometimes is.
The trunk appears to be too thick to successfully bend which leaves us with a drastic chop to remove the straight and generate new shoots to work with.
I don't usually advocate wasting a season layering but in this case, the apex of the tree has some merit so consider layering up high to make the apex into a new tree. That will also go some way to mitigating the disappointment if the next step does not work as well as expected. The middle branch on right also looks promising so you could also layer there for another tree.
Blue lines for possible layers.

The next step would be a drastic trunk chop around the dotted red line. It needs to be chopped this low to get rid of the straight section. Most Ficus sp are really good at growing new buds on older wood so it should respond with plenty of new shoots just below the chop site. Brown lines are where I would hope to develop new trunk and branches.
I suspect that, given it's a Ficus, you should get some new back buds along the trunk after layering so you may even have options to chop to before making the final trunk chop.
As always, my proposals are base on what I can see in 2D photos. Please check the real tree to make sure the ideas offered are practical with the real tree. And never go ahead until you are totally satisfied with the plan.
