React, Node, Angular, Vue? Where and for what?

Question

Frontend

Hello. I work as a sales manager in a company. And my goal is to sell customers the right products and technologies.
I studied a lot of resources, read Toster, habr and other authoritative sources and, to my great regret, I cannot find answers to questions that are simple in my opinion.
There is no accessible language to describe where and for what technologies can be applied. For example, everything is clear with CMS. There are some that are great for corporate sites, something for online stores, something for banal LPs. Features and benefits are outlined. I understand what databases and their types are used for. For example Postgree is faster than MySql etc. I have already figured out even the assemblers (gulp, webpack) :)
And here is a simple question, where to use React, Node, Angular, Vue, etc. I still can't understand. I have a cry from the heart. Dear developers, help me figure it out, right on my fingers. I will be very grateful if you give some examples of where to use React for example. For example: it is perfect for an online store, or a component such as: a shopping cart. But most importantly, why? It will work faster, it will be easier to use. Is it worth using these technologies for simple sites (corporate sites of companies). I read that many trendy frame piles generate code on the fly and that there are many problems with SEO, but at the same time there are already solutions where static pages are formed, they have CNC and search engines index them.
There is a lot of information everywhere, written in complex technical language. But for a simple layman there is no information :(
I really want to sell competently, and what I really need. I don’t want to deceive customers and I’m tired of hovering in the clouds!
Thanks in advance to everyone for the response. And I apologize in advance if my question is somehow stupid
Good luck to everyone! Best
regards, Valeria!

complex technical language. And for the average layman there is no information

A simple layman does not need to know this - these are complex technical things. Not all programmers can clearly answer your questions, let alone a manager...
