Which license to choose for a web resource

Question

Programming

Good day to all. I'm ashamed to admit it, but I don't really understand licenses, so I'm turning to you for help. Below I will try to list all the key points related to the project so that you can help me choose a license.
At the moment there is no company as such, there is a group of like-minded people. The company itself will be registered as an LLC by the release of the project.
There is a project that is being developed (from scratch) by me and this same group of like-minded people. The product is essentially a web resource (one of the site types) written in PHP+MYSQL+JavaScript+Ajax.
It is possible that JavaScript and Ajax libraries with an open license will be used in the project, and CGI written in C or C++ will probably be used.
Server operating system GNU Linux (Debian) with Apache2+PHP+MYSQL installed and C++ compiler
Sources will be stored on a Git server. Development will be carried out on the Linus system using freely distributed applications.
The product will be used by me, on my or possibly rented server and will provide paid functionality for some users of the resource. No one gives them access to the source code.
The project itself is closed and cannot be distributed and modified outside the company (which will be registered by the time of release), and all employees who will work on the project will sign a non-disclosure document.
Actually, I haven't forgotten anything. I may have provided redundant information, but I just thought it was best to include all aspects.
Actually the question itself. Which license to choose for the project and if it is necessary to use several licenses for different parts of the code, then please consult and describe in detail which license to shove. I tried to search for information on the Internet, but mostly I came across articles about free licenses or materials in which I got confused and could not understand anything at all.

Answer 1

If the product is closed, then the product is closed, its own license, write whatever you want there. And as for the libraries used, see their license, in your case you only need to know that the license allows you to conduct commercial activities and allows you not to disclose the source code, that is, absolutely everything from the above.
