Opencart or Prestashop or CS-Cart or ...?

Question

CMS

There is a little experience in developing an IM, they made a store for ≈600 products on wp + woocommerce for customers, it works more or less normally, but now they want something similar, but with a lot more products. There are fears that woocommerce will have problems because the data is not stored optimally and the core generates a lot of queries to the database.
You need to choose cms that would best suit some requirements:
About 1000 products at the start and gradually increase to 10-20 thousand.
Hundreds of categories, a large number of variations in 1-3 attributes, 20-30 attributes for each product, attributes are different for different groups goods.
Adequate opportunities for customization. That is, if you need to add a link to a basket with the number of goods somewhere on the page, then it should be possible to get the quantity and the link via api and then display them in the right place in the template, and not connect a plugin for this that displays the basket in a certain place. Or display only the required fields on the checkout page and create an order based on them.
Good internal api, some wrapper around requests, maybe orm.
System of events/hooks/something else for modifying behavior from your code without touching the core and those parts that will be updated.
The ability to painlessly expand objects with additional fields, for example, add some flag, display it as a checkbox in the admin panel and get it on the frontend, the ability to create a page with settings for the admin panel, for example, with phone numbers, addresses, etc.
The ability to display products of different categories with different templates.
News and static pages, different templates for static pages.
Normal standard store modules: user account, promotions, import, caching, cnc, working with SEO, rights differentiation, filters, etc.
Ability to integrate with the accounting system, crm, work with the quantity of goods.
The theme will be made its own, because customers will eventually require changes to almost everything, but there is an opportunity to spend quite a lot of money on plugins.
I have some experience with laravel and octoberCms, but I don’t want to take frameworks for the base, because the functionality that is already in the CMS will most likely have to be written from scratch, and there will not be enough experience to do it well. Yes, and it will be easier to find people for possible improvements with cms. Bitrix, for obvious reasons, I want to avoid, non-specialized cms like WP and Joomla too. With magento, as I understand it, a lot more money will be spent on hosting, administration, development and plugins, plus the free edition has reduced features.
Is opencart or prestashop suitable for such? Perhaps there are other options?

Answer 1

Bitrix. In a not very expensive edition and a lot of work.

Answer 2

any CMS for IM is suitable, the main thing is that the hands are from the right place
