Well it doesn't specify dragon type/color. Not every dragon has an innate alternate form ability, so hopefully you get one of those.

Age is also an issue. Depending on how old you are, you'll probably be somewhere between young to young adult. If you're at least 50 you can hit young adult. This means you're pretty limited in a lot of things, and if you have your innate spellcasting at all, it's gonna be pretty limited.

If you're one of the dragon colors that doesn't get innate alternate form, you're probably gonna have to hide for the better part of a century just to get old enough to have some decent spells.

So there are downsides, if temporary ones, to the dragon option. Still, it's probably the best choice, yes.
