Learning path for beginners

Hi, lately I am getting quite interested in everything related to AI and its components. I would like you to help me to know a little better about the “state of the art” of the technology. My goal would be to apply this knowledge to record, enter and retrieve valuable information from standardized information systems for SMEs. As far as I can see, there is an NLP course that will be good for me, but I would like to know other resources to complete my knowledge and approach new solutions.
