Why is painting more often associated with art than any other media? what type of painting do you find most interesting? why?

Because it was the dominant art form until the rise of photography, cinema, and digital art.

Explanation:

The painting was the first human expression. Trought the painting, humans could say what they were thinking, how they were feeling, how they saw and understood the world. In other words, it was the only way they knew to register their ideas and postpone them to the future. When humans began to organize themselves in cities, ruled by kings and emperors, art painting became more complex and profitable. The painting now is the way how a governant can show to the future genarations how he was powerful, and art was the way he could do that. As you can see, the painting regards a respectable place in human history. And starting with my explanation, you can answer the rest of the question. Think about the art you saw, and answer yourself: Why I liked that? What took my attention to? It was beautiful? What's the difference between the painting I saw with all the others?
