The Final Fantasy XIV Endwalker Official Benchmark uses actual maps and playable characters to assign a score to your PC and rate its performance including scene loading times.
The benchmark gives an overall load time as well as loading times by scene.
The Corsair MP700 PRO does pretty well in the Final Fantasy XIV Endwalker Official Benchmark. It doesn't top any of the load results charts and even sits bottom of the Scene 1 and Scene 5 charts but still manages to end up in third place overall for the complete benchmark run.
