Today is a cold day. Today is a cold day.

This very much emphasises how cold a day it is compared to other days. If you want to just state that it's cold, you could also say "It's cold today".

Today is a cold day. Today is a cold day.

We won a drawingffle and bought a Switch 2 at a hobby shop! We won a raffle and bought a Switch 2 at a hobby shop!

If you mean you won a 抽選 to be able to buy the Switch 2, I think "raffle" or "lottery" would work best. I would also note that many other countries do not use this system, and things like the Switch 2 or concert tickets are sold on a first-come-first-served basis. This could mean that someone not familiar with how Japan does things that you winning a raffle is separate to buying a Switch 2. If I were rewriting with this in mind I would write something like: "We won a chance to buy a Switch 2 in a raffle, and went to a hobby shop to purchase it."
