She didn't choose the Tesseract because she wanted to conquer Asgard. Why would she need the Tesseract if she's already on the planet? If she needed an Infinity Stone to conquer the world, I doubt she'd have been as much of a threat as she already was.

Now you're just blowing smoke, because you're confusing her motivations with theories. The focus of the narrative was Ragnarok, the death of Asgard. The Eternal Flame is what ultimately led to that, as it gave Surtur the power to do so, which completed that saga.

'Pretty sure' doesn't actually count as solid evidence, since it's a guess. Especially since Hela said it was smaller than she'd thought, meaning she hadn't actually seen it before.
