This is the right way to look at it. Pick the job first, then the model. Your table lines up with how I use them day to day: Veo for short hero clips where audio matters, Kling for people and multi-shot scenes, and Seedance when reference frames need to carry continuity across shots. Two things I'd add from my own tests: re-run the exact same prompts after every model update, and track cost per usable clip instead of cost per render. Running quick drafts in Hailuo before spending credits on the heavier models saves a lot too. Disclosure: I run PixelDojo, a multi-model studio with those families plus Hailuo and Flux. Solid writeup.
