I don't see a lot that's interesting in this tree as it is. Chopping it ensures the trunk won't ever be much thicker than it is (unless you change its growing conditions). Hard pruning it will give you more options but that too ensures your trunk is going to be about this size for quite a while. Both of those are valid options if you're satisfied with the trunk thickness.
Were this tree mine, I'd lean toward repotting it into an Anderson flat. Concentrate on flattening the rootball during repot. Looking at the pot its in now, you may not be confident in reducing it back as far as it needs to go in one fell swoop so cut off any downward growing roots at this repot and lay out the remaining ones so they grow laterally. Next repot cut those back so that you develop interest in the nebari. (It's likely possible to do this all in one repot, but you may need to be creative in securing the tree w/ such a small rootball.) Make sure after each (no, any, ...no, every) repot that the tree is completely immobilized.
This would give you the option of making a more compact tree in the future if you choose, ...or a tall elegant tree WITH a nice nebari.
