To assist you in the best possible manner, I kindly ask that you please provide me screenshots that illustrate the problem to the Private Content area, this will allow me to thoroughly investigate and address your concerns more efficiently.
It is due to different heights of images. I kindly recommend you preparing images you want before uploading them to your media library using the graphic editor (Photoshop or any other) to have a nice-looking grid.
For the Product Archive page, please navigate to Theme Settings > Product archives > Products styles, here you can enable the Even product grid for desktop option to align products if they have different height components. https://prnt.sc/ASt5z0mmasuz
