On top of 'basic' spec, which is not that basic at all, with the 'Edition' you get:
Pilot Assist and Adaptive Cruise Control,
Winter pack with heated steering wheel,
Headup display,
Autodimming Interior and Exterior Rear View Mirrors,
BLIS with Cross Traffic Alert and Rear Collision Mitigation,
Rear Parking Camera,
Smartphone Integration (Apple Car Play and Android Auto),
Harman Kardon stereo.
I may have missed something, the above info is based on online ads, as I'm looking at those too
With the 'plus' it varies, many don't have any of the above extras, most popular I've seen are winter pack and headup display, occasionally xenium pack with 360deg camera.
Best to see the car in flesh and double check everything, as the ads are often inaccurate and list some options the car clearly doesn't have, just looking by at the pictures.
