The "M7" board uses an i.MX RT1011 chip. We have only been working on porting CircuitPython to this chip in earnest relatively recently. The boards that use SAMD chips or the RP2040, or ESP32-S2, are more complete and more stable. The ESP32-S3 is mostly fine, but it has trouble with certain I2C sensors.

So if you want to use an Arduino shield (that can output 3.3V logic), see the https://www.adafruit.com/product/3382, https://www.adafruit.com/product/4775 for example
