For your next visit, maybe install this app:
It let's you buy a ticket ahead of time, so you don't need to bother with the machines when you've landed. And you pay with your credit card, so no worries about running out of Euros. Just make sure your phone still has some charge left so you can show the ticket ...
You can download the Munich transit app, it is called MVG Fahrinfo.

The S-Bahns come every 20 minutes during the day, so you can use the app to plan your times. It is available in English. It is usually updated with delay information, so sometimes better than Google maps in that respect. Note there are two lines, the S1 and S8 which both go to the airport.
OK it seems there is a stop near your hotel which several buses are going to. Unfortunately you are a bit too far to walk from any S-Bahn station (you can walk to Erding in about an hour but you probably don't want to.) Also the buses are not running very late, only until 10:30 pm or so. With the bus, the trip is up to 1:30 long. I would say the least complicated option would be to ride the S1 or S8 from Hackerbrucke to the airport. (they run every 20-30 minutes all night long) Then take a taxi or Uber from the airport to your hotel which is about 15 min and you are guaranteed to find a taxi at the airport which will be impossible around the fest anyway.
In the morning to reach the fest, have the hotel call you a taxi and go to the Erding station (S2 line) because it is a bit closer. All the S-Bahns go to Hackerbrucke where you can walk to the fest like I said before. Splitting a short taxi ride between several people shouldn't be too bad. You would also need the "whole network" group day ticket for MVV, (it is the most expensive ticket because the airport is a bit far from the city) also it covers every bus/train/tram within the system and up to 5 people can share a day ticket for €23.50 (you have to stick together in this case, but if you lose someone no problem they can buy a single ticket for €12.40)

Also I found all this using the app "MVG Fahrinfo" which I highly recommend you to download and use during your trip, it is usually better than Google Maps for transit connections. Language can be changed to English in the settings.

Wow. You may be the first person to nail the public transportation planning in Munich on their first attempt. You _could_ buy an extension ticket for your three day pass to ride to the airport. You will need the App by MVG, add Rings 1-4 as your "monthly" ticket and then buy through the app.
I do think that's a little overboard for saving 3€, nevertheless I'd recommend getting the app. (iOS or Android). All tickets you described can be bought via the app. Add your credit card beforehand and easily obtain the ticket through your phone. The machines can be out of service, confusing or crowded with confused tourists.
Maybe get the MVG app, it will tell you exactly what a given route costs, you can buy the ticket via the app, too:

(There should be an equivalent app on itunes, too.)
Public Transport
App
Get the MVG Fahrinfo app.
It is available in English on both Android and iOS and the best overall among the three available public transport apps. Features a trip planner, live schedules, and the like. You can purchase tickets via the app as well. It's the easiest to handle interface for non-German speakers and you can buy the ticket on the way to the airport. Saves you time spent vacationing while here.
Caveat: Your phone needs a decent battery.
Tip: If you use a maps application and GPS a lot (drains battery), use your partners phone for tickets or vice-versa.
Ticket
Given that you are a party of two and here for a "weekend" (presumably 3 days), get the München Card. Duration of validity can be chosen, range is 2-5 days. A group version is available and cheaper than two individual passes. Last choice is between Zone M (all stations within city limits, 3 days for a group: 42,90) and Zones M-6 (Munich greater area, including the airport, 3 days for a group: 59,90). Former will likely suffice to reach all sights you'd like to see, get the latter should you be travelling by plane.
Payment
Have cash on you. Credit card penetration is extremely low in Germany as compared to the UK or any other country of comparable GDP. This is a surprise to many first-time visitors to the country.
History of Munich
Münchner Stadtmuseum (Museum of the Town of Munich)
Most complete overview over the city's history.
Nymphenburger Schloss (Nymphenburg Palace)
Most relevant palace within the city limits.
NS Dokumentationszentrum München (Munich Documentation Centre for the History of National Socialism)
Munich-focused, but addressing the national history of the time as well.
Bier und Oktoberfest Museum (Museum of Beer and the Oktoberfest)
For the sake of completeness. Touristy AF. But yeah, part of Munich's history.
Christmas markets
Two are so central in the old town, that at Marienplatz and Viktualienmarkt, you would have stumbled upon them no matter what as almost every tourist ends up at these spots, regardless of time of year.
By all means go there and check out the markets too. Crowded and touristy though. More unique and less crowded and overpriced Christmas markets exist though.
Pink Christmas at Stephansplatz
LGBTQ+-themed Christmas market, welcoming queer and non-queer folk alike.
Tollwood Winterfestival
At the site of Oktoberfest. Pretty market. Not all that traditional. Decent quality products, little on the pricey side.
Beer Halls
I'd skip the Hofbräuhaus, if I were you, though it may be the most widely known. Not worth it.
Visit the Augustiner Bräustuben, directly on the premises of Munich's oldest brewery. Frequented by locals as well as tourists.
Augustiner Keller is a good alternative / further option for a "beer hall".
> apologies in advance for our terrible politicians!
No need to.
It ain't like it's your personal fault at all.
Also, we (ze Germans) fucked up much worse in recent history. We managed to elect the guy too. You just left a trade union and shot yourself in the foot. ;)
