We had a rather similar discussion here many years ago (20?) about Optima lead batteries, which used (and still use) cylindrical cells. This thread has named some of the advantages of cylindrical cells. Those aren't insignificant by any means. However, a cylinder isn't as efficient as a rectangle if your goal is to package the most active material per unit of available vehicle space. The exception to this would be a case where the form factor matches the container perfectly, such as filling the round frame tubes of an e-bike with cells.
