It's pretty easy for me:
1) I want to keep all my Photos library originals on my phone -> I need a 1TB phone, since I have roughly 600GB of pictures, taken over the many years since the advent of digital photography (my first pictures are from Dec 2000, when I got my first digital camera, a 2MP Kodak DC3800)
2) I decide it's enough to "optimise" storage for Photos, so I can fit into 128GB, but 256GB give me a bit of buffer for taking long videos, keeping more music on my phone for when I'm on an airplane, etc... it's a decent tradeoff
Downside of 2 is that going back to watch old videos/pictures is not "instant", sometimes it take a few seconds to wait for wifi/mobile buffering to see the picture/video in full quality... but this downside for me is not worth the 500€+ I would need to give to take a 1TB phone instead of a 256GB one.
