Hi Amiraa,
how about making the products unavailable on all of the sales channels? Later, if you do decide to make the product available again, you can just choose the channels instead of creating the product from scratch. Plus, the pages will be still searchable on Google.
Btw. I think that archiving the products also leads to 404 if I’m not mistaken.
The other option is to set redirects. There is one article on Shopify about the redirects - https://help.shopify.com/en/manual/online-store/os/menus-and-links/url-redirect
