Emphasis on the word "may" regarding the markings, but Kaguya did
image the Apollo 11 landing region.

An annoted image here:

Quoted from the Apollo Lunar Surface Journal corrections page:

"Hiroyasu Hayashi calls attention to an image of the Apollo 11 landing site taken with the multi-band imager on-board Japan's Kaguya lunar orbiter. Most interestingly, although the image lacks sufficent resolution to show the descent stage, it does show a bright area around the known LM location, presumably cause by sweeping of the surface by the descent engine exhaust."

As for the urgency to preserve digital information in light of the saga of
the Apollo 11 tapes, check out this article here:

The relevant quote:

“If worries about digital preservation seem premature or overly pessimistic about an eventual solution, it’s worth comparing the success of restoring traditional holdings with comparable digital records. In 1975, NASA’s Viking landers sent back reams of data from Mars, where they were scouring for possible evidence of extraterrestrial life. Unfortunately for scientists, the magnetic tapes used for storage became brittle and nearly unusable even after the space agency made considerable efforts to keep them in a properly controlled environment. Beyond the physical obstacles, moreover, scientists in the late 1990s found that they couldn’t read the data format anyway — and they had to crack open the original (analog) printouts to retype them.”
