Not sure if you've lived here before or in a climate like this, but winter tires are definitely a good idea. I know you said not this winter -- don't worry PLENTY of people rolling around on all-seasons, but I'll just say you should seriously consider it when you can. Personally I think it should be required.
No need to get special winter washer fluid.
No need to get special winter coolant.
But if you do need to add some sometime, make sure you use VW-Audi approved coolant. It's called G13 and is pink in color. I think Pentosin makes some, too, but personally I would just get the OEM stuff to be safe:

Do NOT use something else.
Also, it comes in concentrate and needs to be diluted to a 50/50 ratio with distilled water.
Some other tips:
- Don't let your gas run to empty. I like to keep at least 1/4 tank at all times
- Have a snow brush on hand. I like this scratch-free one

- Have a small shovel on hand
- Get a nice coat of protection on the paint. Wax is good, but a sealant would be longer lasting and less likely to wash off in car washes. Usually requires surface prepping with a clay bar, though.
- Rust protection / prevention. I spray FluidFilm on all of the exposed metal areas of the undercarriage, including the suspension.
- Get touchless car washes to wash the salt off on a regular basis. If you care about your paint, regular brushed car washes will give you crazy scratches. But a lot of gas stations have drive through touchless washes that rinse off salt with high pressure water and soap. Some have underbody sprayers, too. These are not PH balanced and will likely strip regular car wax quickly, but I think it's better to wash the salt off.
- After going through the car wash, make sure to dry the car well. Specifically the door jambs. use a microfiber and lubrication quick detailer. Adam's quik detailer works great. Could go over the whole car with quick detailer or spray wax from time to time to increase protection.
- Get good winter mats if you don't want to ruin your carpets. Pricey, but weathertech makes very good laser-cut hard plastic mats that have high edges to retain water and slush very well.
- Go into the winter season with good windshield wipers
- If you want, you can rain-x your windshield so ice doesn't stick to it as much. Just be careful of surrounding plastics as I've heard rain-x can be bad for trim.
- Make sure to drive your car often to keep the battery charged
- If you can, try to park in a garage. Even if unheated, this will be easier on your car for cold starts
Other safety items to keep in the car, especially on road trips:
- jumper cables
- space blanket
- some non-perishable food like granola bars or beef jerky
And lastly, use your lights and fog lights in poor weather! Way too many people don't use proper lighting when visibility is bad.
Fortunately you'll only have a few bad winter months this year. Welcome to Minneapolis!
