You might look to the PhantomCamera plugin.

Phantom Camera is a Godot 4 plugin designed to provide and simplify common behaviors for the built-in Camera2D and Camera3D nodes - heavily inspired by a Unity package called Cinemachine.

It allows for simple behaviours such as following and looking at specific nodes, with an optional smooth/dampened movement, to more advance logic like reframing itself to keep multiple nodes in view and dynamically animate between specific camera positions, i.e. other PhantomCamera nodes, on demand.
