Is there a historical reason early motion-picture makers chose 35mm film specifically, rather than some other width?

Yes. The commonly cited reason is practical and economical: early filmmakers used existing 70mm film stock and split it in half, producing film about 35mm wide. Because that stock was already available and inexpensive to adapt, 35mm became a convenient standard rather than a carefully optimized size chosen from scratch.
