Under "Publish by web & e-mail" section the short video shows adding a product listing, which looked pretty straightforward to add. Right click, scroll, add product listing.
The template it adds looks nearly identical to the affiliate product links I put together for my site, just a bit different on how it fills it in.
I'm in a similar situation, but I don't really have physical products. I've been putting together my blog using google sites and I've come across a few other e-commerce sites, like Ecwid which I ended up using. I'm not sure if it's temporary or not but they have 5 free listings which I did a quick mock-up for, and that just uses embed code. I can direct people to my Ecwid store ({websitename}.company.site) or simply direct them to my website.com/shop page.
The main difference with Ghost I'm seeing is there's no immediate product page for each shop listing, but that shouldn't really be an issue unless for some reason it prevents you from creating site pages for each specific product.
In short: I would say if you are able to create a shop page with 5+ listings (which you can see details and add to cart), and then you are able to click a product and have it bring you to its specific page to see more details and add to cart, Ghost is probably as good as anything else.
