Cinemachine supports orthographic cameras. When you set the Unity camera's projection to Orthographic, Cinemachine adjusts to accommodate it. In CinemachineCamera properties for Lens, FOV is replaced by Orthographic Size. Note that settings related to FOV and certain FOV-oriented behaviors such as Follow Zoom have no effect if the camera is orthographic.
In orthographic environments, it doesn’t usually make sense to rotate the camera. Accordingly, Cinemachine provides the Position Composer to handle framing and composition without rotating the camera.
When the main camera has a Pixel Perfect component, you can add a The Cinemachine Pixel Perfect extension to your CinemachineCamera to enable it to play well with the Pixel Perfect environment.
To confine the camera to a specific region of your 2D world, you can use the Cinemachine Confiner 2D extension
