I grow both fiddle leaf ficus and narrow-leaf ficus ('Alii') and I think the narrow-leaf would do well in your conditions. Many ficus (Benjamin for example) are horrible plants because of leaf-drop but the narrow-leaf does not show that tendency. I can move my plants from place to place, can neglect them for weeks, and can subject them to low-light situations, and they seem to shrug it all off. Of course, they will grow best in bright, indirect light and when fertilized and watered regularly, but they are very hardy plants. Another good thing is that they grow more compactly than the Benjamin (which gets really "leggy") and don't grow nearly as fast as the Benjamin and certainly not as fast as the fiddle leaf plants. My fiddle leaf ficus plants grow a minimum of one foot each year and my "Mother" fiddle leaf grows two feet each year. The narrow-leaf plants grow perhaps 6" each year. The narrow-leaf can also be trimmed to both control size and to encourage branching.
