For a home setup you aren’t going to be spending the money a double or delta conversion unit costs, so line-interactive is the only sane choice.
You really don’t want line-interactive gear when dealing with larger loads either, as the transformer will just cause extra current draw during a voltage sag. This is why you don’t see (many of) them above 3-5KVA.
