I think one of the reasons for the lack of competition in F1 is the size of the cars. Why not evaluate reducing it?

Yes, the size of the cars does reduce the potential for overtaking, especially at places like Monaco or even on any track where there are slow-speed corners, which is where you would think overtaking should take place.
I have to admit that the bigger, wider cars look a lot better than the narrower ones with narrower tyres and stupidly high rear wings that we had a few years ago, so I would have to say let's keep them and try to do something with the circuits.
