Hi! Just placed my order and have 2 months to learn the software before it shows up. 
Q. What is the best workflow for art pieces?
Based on this…

Then I’m at a loss…does the G script get imported into Fire Control and then run?
Thank you!
Welcome to The forum.
That’s a great start to your workflow.
Using Adobe illustrator to create a SVG.
Importing that SVG into fusion 360.
After moving that design through the CAD "design workspace "environment
In fusion 360.
You’ll run it through the CAM environment " manufacturing workspace" to create tool paths
Once these tool pods have been generated with the proper post processor installed into fusion you can then generate g code.
The G-Code will be a NC file.
This NC file is fire control can work with ( or tap file). loaded up and start cutting.
.
An alternative workflow.
Export your SVG from Adobe
Import that SVG into sheet cam.
Generate tool paths and sheet cam.
Then create g code.
Load that G-Code into fire control
You’re not at a loss at all that’s exactly what you want to be doing.
A lot of guys like using inkscape for design .mostly I think it being free is a big draw.
Myself I try to do everything in fusion 360. But I’m glutton for punishment.
Thank you Tin!
