I still think that you should start with the Python programming language. It's the modern alternative to the "BASIC" of the 80s.
Install the latest stable version (3.16 according to https://www.python.org/downloads/), struggle a bit with the official tutorial (https://docs.python.org/3/tutorial/index.html) or get any introduction book from Anna's archives, and have fun.
I'm an old fart and I don't believe there is a need to write complicated stuff to have fun. Try that for a few hours, struggle a bit because it should be entertaining for your brain, and see if you have fun. If not, there are other languages out there, but Python is easy enough to grasp most concepts like variables, loops, playing with data, and writing simple scripts.
