I would say it's generally better to just use USB dongle. But if you really want to use on-board wifi, then yes, original Orange Pi 3 (not LTS!) version is good bet, but it still need extra binary blob for faster connection. Only other solid choice is Tanix TX6 box, with one of the Realtek wifi chips, although XRadio variant also exists, which is not (yet) supported.
Wifi which is used on all newer Orange Pi boards, like Orange Pi 3 LTS, is not supported.
