I think you're looking for CircuitPython, which is available on a variety of small boards [0]. Based on my, admittedly, very limited experience, I would strongly consider the Feather line of products from Adafruit [1]; they're compatible with each other, most have CircuitPython support, and they mostly have STEMMA QT ports for simple connections to I2C-based peripherals.
