Basically, you will have access to any peripheral with the flexibility and power that Python provides.
I just tested a Bluetooth example in a Xenon board and was blown away by how fast I made it work. A quick overview of its capabilities lead me to believe that Circuit Python is several levels beyond Arduino as a tool for fast prototyping. I also see it as the dream project for anyone wanting to be introduced to the world of electronics, programming, tech art, etc. Here is the tutorial I followed If you want to explore what I just did: https://www.rototron.info/circuitpython-nrf52840-dongle-openocd-pi-tutorial/ .
