What cms to use for large online stores?

Question

CMS

I wonder what cms is the most optimal for large stores? If you want to make a store that is not inferior to brands such as Ozon, M-video, Wildberries.
1. When there are more than 10 thousand products. When there is a need for 1C and import / export of xml, cooperation with the Yandex Market, etc.
2. When there is a need for all kinds of calculations, printing sales receipts and other modern useful functions for an online store. Payment for goods in various ways.
3. When maximum security against hacks and data theft is required.
4. Mechanisms for promotion, optimization. Creation of an affiliate program of the store. Support Center. Forums, etc.
