Hello,
1) Basically the product and categories images are controlled by woocommerce and our theme doesn’t influence.
Woocommerce provides the settings for images that you can find under Appearance >> Customize >> Woocommerce >> Product Images.
You can read our detailed documentation about image alignment and content in the following link:
https://xtemos.com/docs/woodmart/faq-guides/image-size-content-alignment-product-grid/
2) Please try adding the following Custom CSS in the Global Custom CSS area under Theme Settings >> Custom CSS.
.category-grid-item .wd-entities-title {
font-size: 20px;
font-weight: bold;
color: white;
}
Best Regards
.
