All rear wheel drive cars suffer in snow regardless of their powertrain.
Yes, summer tyres are also poor in snow and all season tyres are a better bet.
Even in a 4wd you should turn traction control in snow, its whole job is to stop spinning wheels, which you do need to have.
Thinner profile tyres are better in snow as they dig down, tge reason tge old Defender was better in snow than the current low profile stablemates.
Finally, even 4wd have issues trying to stop.
If this weather was a normal winter situation, do what Scandinavian countries do, studded tyres or snow chains
