Curious if you're also including to take night landscape shots or more so landscape+low light shots.
Either way, depending on your budget and speaking generally, you can typically get away with a fast pancake lens for both landscape and low light situations. Generally you'd want the short focal length to take more in both for landscape and the lack of room when you're out in the town. If you want to expand and get a even faster prime or wider lens you can but whichever system that can provide you with that pancake lens will be a great start.
Granted, kit lens as sun mentioned will be good enough to start. Don't get caught up in wanting better when you don't have the budget for it or the reference for yourself personally to determine how much better the other gear is.
A common advice I've see is to go cheap on the body and spend on the glass (assuming you want to expand down the road) but I don't think that's as relevant for Mirrorless. I would go with the Sony. The sensor will be important for low-light photos. Samsung has yet to make a strong reputation for their hardware and especially glass.
