How can I change my website's URL structure for SEO optimization?

I'm aiming to change the URL structure for my website. Currently my product appears like this when accessed through the collection page: domain/collection/collection name/product name/variant.

I want a uniform structure for this common product on all collection pages, like this: domain/product/product name/variant. How can I make this happen? Redirecting all pages seems impractical for SEO, so I'm looking for alternative options.

Additionally I have one product with multiple variants, and each variant has its own collection. I'd like it so that if a customer clicks on say, the iPhone 15 variant, the loaded product page automatically selects iPhone 15 from all the variants. How can I achieve this?

I've included two images to make things clearer. These screenshots are from another website that has the ideal system I'm looking to implement on my website (which is also built on Shopify).

Hey Ade! Are you sure about your last statement? In the navigation as far as I know you can only create menus and assign them. There is an option to change the product URL but it's just for the handle. Please read my post again. I'm trying to skip the collection and go straight to the product URL from the collection page. That was the initial question. Thanks!
