My lived experience is that I can remember key life events to some extent, but there is no visual experience with it. I don't remember what the last house I lived in looked like (less than 2 years ago) but if I were to visit it, I'd clearly recognize it.
One that kind of gets me is that I can't even picture my parent's faces. I can describe them, I have a ton of positive memories associated with them, and feel very strong feelings of love and affection for them, but despite having seen them yesterday for Easter, I can't picture them in my head. In some ways, that's strangely disorienting. It's frustrating to me to feel such a disconnect from things that are __very__ important to me.
But in some ways, it's freeing. I think I have a pretty strong resistance to traumatic imagery, because once it's gone, it's just gone. If I see something disturbing, it doesn't haunt me. I can't imagine terrifying things (at least visually), so when I compare my experience to friends who have hyperphantasia (or at least a decent ability to picture things), there's a lot that can get stuck in their heads that I just can't.
I try not to view the aphantasia as a good or bad thing. It's just part of how I am.
