You can tween pretty much any property(color, scale, position, rotation, modulate, etc) check out the arguments in the tween function.

Here is the doc page for tweens: https://docs.godotengine.org/en/stable/classes/class_tween.html#class-tween

You can see you make a tween using

var tween = get_tree().create_tween()

Then you call tween_property. The arguments are: node to tween(your camera), property to tween(the rotation), desired end state(rotation at the end), time in seconds.

tween.tween_property($Sprite, "modulate", Color.RED, 1)

There are all kinds of fancy tweeners you can add on for making things run one after the other instead of in parallel, having smoother transitions. It's all in the docs and then fiddling.

Good luck!
