Node-RED is a great place to start. It will let you minimise any programming while allowing you to construct logic by stringing nodes together.
There are lots of courses and tutorials for Node-RED, a quick search will turn up several that are worth having a go at to see what suits you - there are so many ways to learn, it is hard to pinpoint a single recommendation.
The main thing is to try and come up with a simple-ish idea that you would like to implement that will tweak your interest and will act as a catalyst for your learning. For example, perhaps you would like to have a sensor to measure temperature and humidity around the house? Or maybe you would like to sense movement in the house, create an automated plant watering system, detect when your washing machine has finished? All of these you will find as examples on the Internet and all can use Node-RED to help orchestrate things.
If not IoT then perhaps a simple web page to gather the latest weather in your area, pull out some key elements and display them. All again very straight-forwards with Node-RED and you will certainly find examples of these right here in the forum or on the flows site that is linked above.
Find an idea, break it down into parts then try to work out how to implement each part.
