Find scene boundaries and center camera vertically

Hi! I would like to run a script function on a specific UI button click, that shows a vertical view of my scene.

The problem is that my scene is dynamic, specifically the Objects in the scene get created by running a script that reads a txt file with object names,types and position/scale/rotation. That means that at any given time the user can load a new "enviroment" in the scene.

Now, the approach I was thinking of is to :

a)find (somehow) the furthest object coordinates in each direction (x,z)

b)center my camera in the middle and move it high enough on the y-axis so it shows every object in the scene.

Has anyone done this before? I mainly wonder how to effectively "grab" the boundaries of my scene (it only needs to happen once on click) and if there is a function that makes the camera fit the coordinates.

Thanks in advance!
