The optimal choice of CMS for an E-commerce site?

Question

CMS

Good day. Question about choosing a CMS for an online store.
Key parameters:
1. Quick launch (3 language versions)
2. Integration with 1C
3. Fastening payment systems, delivery services (both European and Russian)

Among the potential options I consider:
1. Magento
2. Shopify
3. WooCommerce
4. Bitrix
5. Modx

There is an en-version of the site on Bitrix, but adding additional features takes a lot of time.
For example, in the same WooCommerce, they are easily solved by adding the appropriate plugins.
There is another nuance, which consists in the fact that the code of the old site was taken as the basis (which was all the time on Bitrix) and the functionality of the updated site was gradually added to it.
The main question is how much the change of CMS will throw back the current work and possible launch dates.

It seems like they don’t change horses in the middle of the crossing, but ...
I would be grateful for the help and possible arguments in favor of one or another CMS.

ps: I will also consider your CMS options

Answer 1

Well, with the needs that you have and if you want to implement everything at once, the best solution would be self-written.
If you still decide on a CMS, then many choose Open Cart, some take Magento, but I heard a lot about an hour of a developer on Magento. And in time, even small finishes come out a lot. It is clear that over time you may have new Wishlist to improve the site.
Bitrix norms option for you, a lot of things have already been implemented and sold for little money on the Bitrix marketplace. And integration with all possible systems and services.
The only thing that the control panel can be difficult for a beginner is a bunch of settings that are not clear. In Bitrix, you really need to sit and understand. But on Bitrix, I would use some kind of template solution, not individual development. Then things would go, they would switch to self-writing.
And I forgot, you will also have to figure out a lot of time in the template, there is an option that you will customize the template for money, and there all your Wishlist has already been implemented, you just don’t know how to turn them on. And the developer will not understand and show you everything. As a result, your site will have a bunch of extra code that will load your resource.
At my old job, the site was made on Bitrix, because of some solutions from the marketplace, which would be expensive to implement. We were worried that the site would take a long time to load or we would encounter something else that was not pleasant, in principle everything was ok, now I don’t know.
Here's the project if you're interested.

Answer 2

Everything is ready in Bitrix.

Answer 3

Think about why before you change.
what will give you for example English? what are you going to sell there from a local site?
promote in the language of the local market, that is, in a familiar socio-cultural space. If everything goes so well that other languages ​​are needed, you will already have enough income to hire specialists and translate to another CMS
, solve problems as they become available.
the maximum that you may need right now is a payment system, again for the market where they buy from you.
Moreover, the payment system should have a bank account and other legal registration of the business.
