Sql ou Nosql

I'm working on a project where I'm going to have a scraper that monitors the results center of each company listed on the stock exchange. Each company's results center does not have a standard for naming and data. I'm trying to do this with MySQL and my code is very confusing.

I've never worked with nosql, and from what I've seen, mongodb could be interesting.

What do you recommend me? Would it be more appropriate for me to store each company's data in a single collection with mongodb?

Just to give you an idea, see the results center of two companies:

https://ri.naturaeco.com/resultados-e-presentacoes/central-de-resultados/

https://ri.cemig.com.br/divulgacao-e-resultados/central-de-resultados/2021

The names are different, and organizing this in MySQL is a bit confusing.
