I’m not an expert, but the first thing I learned is that bonsais are all outdoors. It does not matter what the nursery tells you, none will develop well inside a house. Any tree will eventually die due lack of light or if surviving it won’t be healthy and will definitely make the leaves bigger to get more light.

That being said if you are still fixated to ignore my advice above and try to get a tree anyway, probably a ficus is the best option as they are one of the hardiest species and it won’t die if placed in interior
