No such thing as a stupid question here, and don't let anyone tell you otherwise.
Indoor kites provide ultralight abilities, versatility, and a little more durability than an ultralight "outdoor kite"... The outdoor versions are generally higher performance, but tend to be a little more fragile, requiring a gentler, more skilled hand.
Based on what I've read from you so far, it sounds like an indoor kite might be the best choice for now... Along those lines, I tend to favor the Wren and iKnack as having good lift, and for their durability.
I hope that helps.
