No disrespect OP because I know you're trying to be helpful but based on all your comments here, it sounds like you're assuming everyone uses their phone the same as you (e.g., "I’ve personally taken over 100 gigabytes of photos and videos in a single day on a 13 pro.") and it's all coming across as
extremely condescending ("Guess you don’t take any movies, listen to any lossless music" or this one: "It;s all of these 128GB, 256GB ppl that will be sorely mistake I am sure. Again, I have a 13 Pro 512GB so what do I know?

").
Most people do not take 100 GB of video and photos in a day. Most people do not listen to lossless music. Many people take video. They can offload that video to a computer or cloud storage if they run out of room. Or, they might just go back and decide an old movie isn't worth saving. Not everyone is a digital packrat.
"Have a 512GB iPhone 13 Pro, and it’s filled. In fact I can’t count the number of times I’ve had to ‘free up space’… so awkward. Thank me later."
I have an iPhone 13 Pro with 128 GB and it's not filled. I've never had to free up space. If 512 GB isn't enough for you, get more storage but don't assume everyone needs more.
