Not the richest fastest but probably nice and discreet: electronics repair shop using mending.
You can’t mend to fix magic smoke problems. Though it would be awesome to run your finger along a cracked screen to repair it
I think you would be able to
You can fix constructs and magical items with it, you can’t put magic back into it though
Mending was my first thought, admittedly because of Harry Potter And The Natural Twenty. D&D munchkin gets mis-summoned into Hogwarts, and spends a few hours every evening doing all the stuff the rules as written say his character can fit into an evening. He’s still incapable of any magic the school teaches, but now he’s got a bag of tricks a mile deep, and his robes look fucking incredible.
Why stop at electronics. I would think just going to a scrapyard and repairing machinery or vehicles back to working condition would be massive.
Take 20$ in scrap and turn into hundreds of dollars by repairing.
Lawful Good:
Foresight to convince the smart, powerful people that they’re making bad decisions, influence them to make better decisions for the world, only use it for enough personal gain to sustain a decent living.
Neutral Good:
Mass Suggestion Convince the dumb powerful people I’m a divine being and they better do as I say, use this power to force positive change amongst the easiest to control masses. Collection plates at churches now go to me.
Chaotic Good:
Gate, Use teleportation to extort billionaires by witnessing their depravity and threatening them with exposure, also portal tech. become Rick Sanchez. Rob swiss banks for fun and profit.
Lawful Evil:
Meteor Swarm: Hold cities hostage for ransom.
Chaotic Evil:
True Polymorph: I’m going to start turning politicians into lizards. For cash I’ll turn random shit into itself but but made out of a different material and auction if off, passing myself off as a great artist of incredible talent.
Edit because I forgot about the money half way through.
I’m torn between targeting just the worst world leaders or targeting them at random. The end goal would be making every politician understand that a mysterious force WILL turn you into a lizard if you displease it. There will be no indication of what displeases the mysterious force.
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.
