How to make a normal camera in unity?

Question

Unity

I want a normal camera in my game, I need a camera that is quite simple, as in ordinary games, it follows the character from behind, with the ability to look around with the mouse or joystick, and of course, so that when there are objects in the frame that interfere with observation, the camera goes around them, or looks through, so that the character does not fall out of sight.
I have already tried several cameras from the asset store, not one is suitable yet.
I learned that in unity they use Cinemachine for the camera most often, but I don’t know how to make observation on the sides in cinemachine, and when objects in the frame that interfere with observation, the camera went around them, or looked through them so that the character did not fall out of sight, I can’t do it.
Please tell me how to implement this in Cinemachine, or tell me normal cameras, I will be grateful))
