After digging myself into the (honestly not really thousands amounts of resources ) I have stopped by this Princeton's tutorial http://data.princeton.edu/stata/ and this one https://stats.idre.ucla.edu/ . The second one is also good, even if you are only starting to learn statistical programming.
Another thing to take a look at is this page: https://www.stata.com/bookstore/stata-press-books/ . Could be helpful on finding what is relevant for your research.
