As you are staying on a weekend, there will be plenty of bars, clubs and other entertainment locations open till the early morning. Some of them may be loud, some quiet, so you can pick depending on what you are likely to be in a mood in after the concert.
Here’s an english website listing many options: https://www.wien.info/en/lifestyle-scene/nightlife
Note that in general, Vienna is considered a very safe city. So you should most likely be fine no matter where you stay, but as everywhere else, a public place is a good option.
If your main concern is that you have to pay for a hotel room for the entire day but would spend only a couple of hours in it, maybe you could opt to leave Vienna later in the day or early evening instead of early morning.
That way you can relax after a possibly tiresome concert, wake up fresh, then either spend time in the room or explore Vienna a bit (if you haven’t already) and then take a train to your final destination later in the day. I feel this option would be safer than opting to stay out in the open (even if its in a 24-hour McDonalds). You could cut your cost by some euros by staying in a dorm instead of a hotel room.
For 5.8€, you could get a transit day pass that allows for unlimited travel on the transit network, including night buses – (especially) if you take a seat next to the bus operator, you’ll definitely be safe, and you’ll also see some more of Vienna.
Update May 2022: both McDonald’s are closed overnight.
There are only 2 McDonald’s in/near Vienna that are open 24/7 (and even on the Chistmas and New Year holidays):
Their restaurant finder has on option to restrict the search to restaurants that are open 24/7: go to "Detailsuche", tick "24h geöffnet".
All the Burger Kings and KFCs are closed during the night.
As @FDMS notes, the only transit service to the airport that runs 24/7 (though very infrequently) is the Vienna Airport Lines bus service (network map), which costs 6.5 € per direction. The last train to Wiener Neustadt, which is over one hour away from Vienna, leaves at 01:01 from the main train station (Hbf).
