Hello @Alex_Strange, welcome to the community!
So what you have to do is first limit the numbers of products you show on your first row
Then you want to set the display of your collection list to grid
and then on the products that you want to be taller set the columns to 1.25 fr instead of 1fr
And that should work for your first 5 products, repeat the process for the other 5 products. I hope this helps!
