Total noob wanting to make a top-down 2D game

Unity Engine
1

I’m trying to create an initial prototype for design/testing for what will be a top-down 2D game. It isn’t very clear how I do this. What do I set for the ‘floor’? A 1900x1200 Sprite(image) and then overlay sprites on top of it? Do I actually orient the MainCamera so that it is pointing down in the 3D space or is the default way OK?

The game area will take place over a larger area than will ever fit on one screen so there will be panning and scrolling, etc.

It is likely a stupid question, but none of this is clear to me right now.

No, 2D is only in the x/y axis. So you can say y = forward. You can use a sprite or quad as the background, sure.
