The short answer
At about 3 MB per photo, 256 GB holds roughly 85,000 photos. At about 350 MB per minute, the same phone holds about 12 hours of 4K video. Apps, the operating system and system data use part of the advertised capacity, so leave headroom.

Capacity table (before system overhead)
| Storage | ~Photos at 3 MB | ~Minutes of 4K at 350 MB/min |
|---|---|---|
| 128 GB | 42,666 | 365 min (6.1 h) |
| 256 GB | 85,333 | 731 min (12.2 h) |
| 512 GB | 170,666 | 1,462 min (24.4 h) |
| 1 TB | 341,333 | 2,925 min (48.8 h) |
Picking a size
Advertised capacity is shared with the operating system and apps. If you shoot a lot of 4K video, stepping up one storage tier is usually cheaper than buying cloud storage every month for years.
