An idea worth pursuing I guess. My first question: in case this gets forgotten about in the distant future, how could it be marked so there’s a good chance of being found?

Well… the Moon’s surface is also constantly bombarded with rocks… in fact it intercepts a lot of objects that would hit Earth. For this thing to be really safe it would have to buried somewhere, not just left out in the open.
Definitely underground. The temperature swings would be wild otherwise.
Also the full force solar radiation. That’s probably not good for DNA samples either.
