This is basic aeronautical engineering. Barring the need for redundancy, turbofans are most efficient and quieter with larger intake sizes, the main limiting factor being fan tip speed.

This is the reason that the 737 had the MCAS stuff. They increased the size of the engine that caused ground clearance problems, which required shifting them.

Note sure this is reliable source but “ In general, twin engine aircraft allow for faster speeds, and faster pickup...”[1]
