Is there a powerful web engine that combines an internal portal, an external site (s), an online store?

Question

CMS

Hello. Tell me if there are any ready-made options for solving my problem:
a web system that combines an internal portal, external company sites and the company's online store.
We looked in the direction of "hybris", but it turned out to be expensive for us.
Requires very good extensibility to the needs (and there are quite a few of them) of the company.
Thank you for your attention.
