Hello,
You can set grid view on the shop page using this option https://prnt.sc/z0brkb Or even disable the advanced type of the view https://prnt.sc/z0btox
Add the below code to Theme Options > Custom CSS to make images smaller
.content-product .product-content-image img, .products-list .content-product .product-image-wrapper img {
width: auto;
}
