Hello,
If you want to remove the sidebar for the home page content then edit the home page and remove the column with the widgetized sidebar element https://gyazo.com/0139d81ac589b5f9c058fa08700a9f7a
Use products element if you want to display products on the home page use Products element https://prnt.sc/1t8px8j and using products element settings you can display products from the specific category or all the products https://prnt.sc/1t8q3nd , featured products etc.
