Using Arduino and Raspberry Pi together?

Is there any consensus on the best way to use Arduino and Raspberry Pi together? I have a Rebot project that makes use of a lot of Qwiic sensors and Sparkfun Arduino libraries. And I have a Raspberry Pi project that mounts a camera on a platform whose x and y coordinates are controlled by two servos, which processes images and streams them via wifi. I like the abstraction that the Arduino provides for input and output, and I like the high-bandwidth processing power of the Raspberry Pi.

Is it normal to use the two together, or should I pick Pi and stick to it?

I’ll answer my own question: yes it is perfectly standard to use Arduino to abstract sensors and motor control, and connect it to RPi via USB for computational heavy lifting and extra IO.
