I feel similarly. I’m definitely not always going to lug along my FF mirrorless camera, so the iPhone is the camera I’ve always got with me.
Due to the machine learning powered HDR abilities of iPhones, and their excellent color science, it’s pretty tough to beat a new iPhone for pleasing looking snapshots in harsh sunlight. With my FF camera I’d shoot in raw, underexposing to avoid blown highlights, then I import the photo to my computer. I pull the shadows pretty hard, adjust the levels and colors, then I AirDrop the photo from my computer to my iPhone to double check, then I post it. I could have just taken the picture on my iPhone and posted it in seconds, and it probably would look just as good in instagram or Facebook.
