Easiest way would probably be to create a new category called "Latest Products", add all products that you want included and then set the Sort Type as "Newest".
Luckily there is an auto-populated page with your latest products. Add the following to the URL which shows all products sorted by newest: /collection/?sort=newest
This URL can be added to a banner or navigation to direct customers to your newest products.
