I want to build a 10x12 shed like a house for a mini-gym (2x6 framing, insulated, gypsum, flooring, etc).

Is a 4" (3.5" actual) at 3000 psi with 3/8 rebar good enough?
Do I need some compacted gravel at the bottom? Or thicker 6" (5.5" actual) better?

I'm in California, my dirt quality is here: https://soilseries.sc.egov.usda.gov/OSD_Docs/V/VISTA.html

The location photo is attached below.

4" is good for the concrete. Consider a vapor barrier and insulation under the slab.
It will help with any moisture that could come through the concrete and be very beneficial if you choose to heat or cool the area. Granted it won't take much for a 10 X 12 shed.
