To maximise staying under the radar, probably fabricate. You’d not be amazingly rich, but you could establish a decent living with a lot of free time. If you want to be amazingly rich and you squint hard enough at fabricate and what tool proficiency count mean in the modern world you can probably make some bank with a bit of study of chemistry or engineering. Being able to magically create complex drugs or something is going to draw attention though.
Fabricate would work fantastically, and I think you’re underestimating the amount of money you can make with some craftsman stuff.
People will pay a lot for well done custom made stuff. Knives, swords, furniture… all of it is worth a sizable amount once you have any kind of reputation and start taking commissions. I mean thousand dollar chandeliers and multiple thousand dollar tables.
You also can’t use it to create items that ordinarily require a high degree of craftsmanship, such as jewelry, weapons, glass, or armor, unless you have proficiency with the type of artisan’s tools used to craft such objects.
So you’d need to be half-decent at making a thing the hard way, before you can bang one out in ten minutes from a flawless slab of raw metal.
… no, hang on. You only need to be half-decent at using the relevant tools that would make a thing the hard way. So if you take a shop class you can make aerospace-grade parts. Or, less likely to be audited, and making use of the five-foot-cube limits, you can make some lovely garden sculptures for upper-middle-class schmucks.
