How would you list your products on an e-commerce site?

A family member of mine is selling homemade soap, candles and reed diffusers.

There will be 3 different product categories, 8 different scents, with new scents being developed and added over the coming months.

What would be the most efficient (not easiest) way to setup product listings?

My HTML and CSS is ok and I'm currently learning C# and ASP so I primarily use Visual Studio.

Would it be best practice to learn and use an SQL database to store the products and then format them onto the website?

Should I just list the products on the page since there are only going to be a small number of products to start with?

Does using an SQL database make it easier when implementing a shopping cart?

I guess I just need to know how you would generally go about it so I know where to get started.

Thanks for your time.
