Which engine is better to choose for a showcase site?

Question

CMS

Good afternoon dear community.
In short - there is a simple corporate website with a simple showcase (practically, a gallery, on fancybox)
sepo.lightseeker.ru/goods-card.html
There is no basket and never will be, there is no cash register.
The task is to put it on the CMS. The client wants to be able to change the photos of the goods (there will be about 40 of them). Add them, remove them. In general, that's all.
I worked on a lot of things, but there are not a lot of sites created from scratch. There is nothing to compare. You can't go wrong. Someday it will be redone. Himself a coder with front-end skills, nothing more.
1) What CMS advise to choose for this task and why?
2) What is better, CMS tailored for online stores (Opencart, Magento, ImageCMS ...) or Wordpress + Woocommerce (MODx + minishop2)?
3) Is it possible to link the fancybox gallery to the showcase or will I have to use something like a showcase module (so that the admin can edit the photo)?
4) "Normal" period of template integration into CMS?
5) Do you need knowledge of PHP in this case or will it cost?
6) Who has experience, please compare the difficulty of entering the proposed CMS (if there was no experience in this CMS before). Terms, maybe.
I choose between:
1) ImageCMS.
2) MODx + minishop2.
3) PHPShop.
4) UMICMS.
5) Amiro.
6) Simple.
Or is it better to go simple. There are such "simple" solutions as
7) GetSimpleCMS (much easier, but is there enough functionality).
8) Santafox (also VERY simple).

Answer 1

MODX + minishop2

Answer 2

you can just modx without a store add-on (if the basket and the online store module are not needed)
if there is a layout, then on modx you can pull the whole thing with filling in a day or two,
displaying images on the site from the admin panel, the pictures turn into fancybox without problems
for the simplest php solutions are not needed, only for specialized solutions
