The answer to your question really hinges on exactly what you have in mind when you say, "catalogue my photos, short videos and do some light editing."
You could certainly upload photos & videos and organize them into folders. I do not know what photo/video editing apps are available under Chrome OS.
As OldPhil said, doing some web research on that as well as photo organizing/cataloging software under ChromeOS would be your best bet. You should also consider an inexpensive netbook that runs Windows, as the price differential is minimal and (if you're a Windows user, and it sounds as though you are) you'll be able to have a far more familiar world and work experience. Even the cheapest of Windows laptops can easily be used for the tasks you outline, and they're not all that much more than a Chromebook, either.
Also, be sure to purchase a backup drive as well. You do not want your photos and videos to exist strictly as a single copy.

. . . the presumption of innocence, while essential in the legal realm, does not mean the elimination of common sense outside it. The willing suspension of disbelief has its limits, or should.
