What is the best CMS for a simple service store?

Question

CMS

I need a site for a store of services and files.
I want everything to be extremely simple, that is, a showcase of goods in catalogs with pictures, a couple of parameters and a buy button, and services are not ordered in piles, so I want without a basket. And the most simple order form - a contact field for communication + a comment field and after that the transition to payment (WM, YAD, QIWI, bank card)
I tried Opencart, but there is only one terrible order form worth it. Of course, the code there is not very complicated, but there is sooo much to cut out for my purposes.
I tried WP+Woo, also a lot of extra stuff.
It turns out that writing from scratch that cutting out too much from the store's CMS is a lot of work. Is there a simple solution out there?
PS. Free and preferably also open source, so that you can finish the file with a file for yourself various subtleties

Answer 1

So far, the simplest option that I came up with:
Wordpress
+ tile theme (for example, pinbin)
+ PHP Code plugin on which I will write a product card template
. , description, etc.)
if anything, it will be enough to edit only the template

Answer 2

What if ecwid? I haven't watched it for a long time, but once everything was as you described.

Answer 3

I don’t agree with you about OpenCart ... you just need to replace (install) the Simple shopping cart plugin and then all the bulkiness will go away (you can install this module yourself / there is nothing complicated there)
You can also look at the ImageCMS Shop, it’s very easy to use .
