I agree with you, but I would add stuff serving as a reminder. It may be also something you or people you know made. As for reminders think about a story from your life you like to tell people. I have a few photos like that, for example a parrot I have found one day. Landscapes can also work for this. I have a photo in Belvedere in Potsdam, it was a beautiful sunny day and the photo was nice even if made with 1st gen Moto G, I'm always reminded of that day just looking at that photo. Or a photo of a view from window in Supetar, Croatia. I also prefer pictures of people, but I would generalize it to pictures that help form a memory, most are connected to people.
