Autoflower and feminized get listed as if they were rival choices, which trips up a lot of first time buyers. Feminized describes the sex of the plant, autoflower describes what starts flowering, and most autos sold today are feminized anyway. The three column comparison on https://queenfeminizedseeds.com shows photoperiod feminized plants taking three to five months with full size control, against seven to nine weeks and smaller yields for autos. For a fixed indoor tent I prefer photoperiod, because deciding when to flip is half the point.
