Magic as intelligence only is pretty much held only up by convention but lets forget that for a second and bring up Dungeons and dragons. Here are all the stats in dnd that are used for it
1) Intelligence: Typical arcane study
2) Wisdom: Clerical study, empathy, and philosophy. Spiritualistic
3) Charisma: Self-sourced magic, you bend yourself and thus magic occurs
4) Constitution: Natural aspects of your physical body/form that are magical in nature.
The reason why Strength works for Polymorph is that it can be seen as something that "enhances" your current form. The stronger you are the stronger your form is.
Constitution and intelligence also works. And while Dex isn't immediately obvious there are indeed settings where shapeshifting definitely makes sense for dexterity (where it is described as physically contorting your form into desired shapes)
The point really is don't be so stuck in convention.
