Upsell display on desktop is slightly broken

Hi, there’s something weird with the upsell display on desktop in my store (pic attached). Can you help me fix it? I don’t like how the rightmost item (or left and rightmost when I click to the right) go outside the box. If possible, I’d also like to change up the styling a bit:

– Make the added product’s picture larger
– Make the “go to cart”, “continue shopping” and “checkout” buttons larger
– Remove the variation details (-39, Beige) from the display

Best regards,
Mariusz
