Hello there enthusiasts and experts!
Here I am again! Excited to share that soon my fiancé and I are going to a nursery to get some more plants! Among them, she wants another jade, and I want fukien tree and elms.
For now, I got this Sygizium Boxifolium and it's doing amazing!

Corrected some horrible things they did at nursery where I got it, like leaves cut in half etc. she's green, and enjoying Florida weather. For now, I am open to your ideas of what to do with ir soon! Around March I'll repot it and we have an order coming soon (finally), of akadama, pumice, and lava rock. We have already fertilizer, and we are excited to provide even better conditions to them.

I am not very enthusiastic of that weird ball shape of then plant, and the trunk already has some curvature to it. What should I do? I want to make it have a nice canopy, maybe following the trunk's shape?

First thing I would do is to remove the wire and cut that two twigs held tight to the trunk by that wire. None of them is doing anything in my opinion.

I second that. Or bend them downwards by wiring them properly. (This is a textbook example of how wire is not used when training bonsai.)

I think you need to learn a few things about bonsai:

1. Wiring
The way it is wired is not right. It does not help you to properly place/shape the branches. Now, I guess many people don't always wire perfectly, as long as it does the job. This however isn't doing its job.

2. Styling
The lower branches growing up against the trunk do not make sense. I probably would not remove these branches though, you can use them to grow a fatter trynk.

3. Plant selection
I'd always go for native trees, or trees that are known to do well in my local climate.
I have never owned a Carmona and I never will. I have had jades, but I do not find them interesting for bonsai and will not try them again (noticed you're in Florida though, so... I guess they work for you).
Elm is a good choice.

Please take a look at the link below.
It's a very good free video by Colin Lewis, about wiring.

How exactly do you use the lower branches to make a "fatter trunk" ?

Just leave them to grow.

Have a look here at a picture of one of my trees: www.growingbonsai.net/sacrifice-branches-for-trunk-development/

Low branches help to thicken the section of trunk below the branch.
