Choosing iPhone Storage Sizes

I currently have an iPhone 11 (128 GB) and I also have an iCloud subscription. In total, I'm currently using 150+ GB for everything. Throughout the 4 years I've had it, I had to delete lots of files (estimate would be 60 GB worth of files deleted).

I will be getting a 15 Pro Max in a few months, and I don't know if I should get the 256 GB (with 200 GB iCloud) or the 512 GB? I'm planning on keeping it for at least 4 years and with the constant increase in app sizes and implementation of desktop-level games to the iPhone, I want to have a worry-free experience in the next 4 years.

Here's how I use my iPhone:

1. Medium to Heavy Gaming.
2. I always watch Youtube, sometimes Netflix, and I always scroll through IG.
3. I do not download any from Netflix.
4. I love taking pictures from time to time and I sometimes take random videos.
5. I edit pictures and videos sometimes and it takes up 10-20 GB.
