I have a 12mm low-distortion, fixed-focus, manual M12-mount lens marked for a 1/1.8-inch, 10MP camera. What kinds of cameras or applications is this type of lens typically used for, and what field of view should I expect compared with full frame?

Your description includes “10MP” which describes a camera, not just a lens.
Cameras and lenses with M12 mounts are commonly used in compact, space-constrained imaging applications like security cameras and robotics.
A camera with a 1/1.8” sensor has a 4.8x crop factor, so a 11mm lens would have an equivalent 52.8mm standard view when compared to a 35mm full frame camera format.

This is typically an industrial/board-camera lens, not a standard interchangeable lens for consumer cameras. M12-mount lenses are commonly used on compact cameras in space-constrained systems such as security cameras, robotics, and machine-vision setups.
The “1/1.8-inch, 10MP” marking refers to the sensor format and resolution the lens is designed to cover well, rather than meaning the lens itself is a camera.
On a 1/1.8-inch sensor, a 12mm lens gives a much narrower view than 12mm would on full frame. Using the crop factor mentioned in the community answer (about 4.8x), it’s roughly similar to a normal lens on full frame—around a 50–58mm equivalent field of view. So despite being 12mm, it won’t behave like an ultra-wide lens on that small sensor.
