Depends on where I'm going, the vast majority of times it's just the basics, key, phone, maybe wallet.
If I'm going to be on my own for a significant period of time, e.g. taking the bus, I'll bring my earphones. My backpack always has a power bank in it, so if I'm going anywhere that needs a backpack or when I'll be away from home for the majority of the day I can ensure I'll have battery until I get back.
If I'm going to be walking a lot I always bring my an insulated bottle of cold water on my backpack.
If it's winter I'll be wearing my jacket which is waterproof so I'm covered in case, in summer I usually don't bother with it now (before I was living in Dublin and would just go out with my jacket on summer, it's not like it was hot anyways).
I think that's it for my EDC. I do have a bunch of specific stuff for travel, but I think that's beyond the scope here.
Edit: forgot to mention, my backpack also has a pocket with paracetamol and mints, and has a hand sanitizer clipped to it.
