From your OP, you mentioned you were 15 when your mom became USC and in derivation, you. If I interpret the above passage correctly, you actually are still an Austrian citizen. Technically, you should still be able to apply for a Austrian passport. You could also still have a shot at getting a permission for dual citizenship since you did not originally consent to the derived USC.
Mov, you can't have the cake and eat it... if your intention is to move to EU/Austria to live and study there, you wouldn't fulfill the requirements of a US LPR, even if there were a way to "demote" from USC to GC (which does not exist as others said before).
I've lived and worked in the EU as a non-EU (and non-US) citizen: other than having to deal with the work/residency permit bureaucracy (which is universal as in every other country...), there's no serious drawback to retain your USC and live/work in EU.
Renouncing your USC is a complete one-way road, too. When visiting the US, you're back to the status of an Austrian tourist, no work authorization, certainly no GC. My advice would be to defer your decision for your citizenship until later when your life plans get more concrete and you fully established on which side of the Atlantic you're settling
The incomplete, loose translation for non-German speakers: ... a minor 14 years or older will only loose the (Austrian) citizenship if he/she has explicitly given consent to the foreign citizenship...

The passport issue date is not the relevant date, check your US naturalization certificate (which has likely an older date). But yes, it means that your were too young to require your consent and you likely cannot retroactively apply for double citizenship, sorry.I looked at my US passport and the date of issue is 2005 a few days before my birthday (my date of birth is 1992). Which means I was going to turn 14 a few days later. Crap, that may be an issue.
Even if working in the US is not in your stars, your visits to see your parents would be completely on the terms of B1/B2 (or visa waiver), i.e. you cannot visit longer than 3 months (6 with a B1/B2) and not longer than 6months in a 12month window. Also, every time you'd visit the US, you will need to convince the IO at POE that you will return back to the EU (i.e. have a return ticket, have a place to live in EU etc). Your parent's USC will not help you in any immediate way and might only make a IO more suspicious.Since my parents are now USC, then I would be more then fine with giving up US citizen for EU, also given the fact I would be studying/living in EU and possibly also Armenia. The important thing is I could visit US without needing visa, that all it matters I don't care about the working issue.
You mean relinquish your USC? Yes, afaik, you can relinquish your USC at the US embassy/consulate in Austria (after you reclaimed and regained your Austrian citizenship).If I go to Austria for a year in a couple of years, could I just do everything there? In the worst case scenario, I will just re-acquire it there (and will have to relinquish USC).

While it is true that the certificate of citizenship, obtained by filing N-600, would be required in order to see the exact date that the US recognized Mov's citizenship, in this case the passport itself is enough to know that the citizenship was granted before age 14.The passport issue date is not the relevant date, check your US naturalization certificate (which has likely an older date).
