I was planning to keep it indoors. is it relatively easy to take care of for you?
As already said in this topic, Jacaranda's belong outdoors.
If you want to grow bonsai, you need optimal conditions for the tree. Indoors, these conditions are not ideal. The tree will not thrive and it will be hard to keep it in optimal health. If a tree is not in optimal health, you cannot work on it.
In other words: you cannot grow a jacaranda indoors, and trying to grow a jacaranda indoors as a bonsai is completely out of the question.
