There is no distinction of the sort in the law. e.g. California:
(3) “Fraud” means an intentional misrepresentation, deceit, or concealment of a material fact known to the defendant with the intention on the part of the defendant of thereby depriving a person of property or legal rights or otherwise causing injury.
Fraud doesn’t require someone to be "tricked into giving something for nothing." Courts have long recognized that it’s also fraud when one party induces another to act (or refrain from acting) by relying on false or concealed information.
That’s why there’s piles of case law on fraudulent inducement (getting someone to stay in a contract by making untrue statements) and fraudulent concealment (hiding negative information so they remain in the relationship). In both situations, the injured party continues performing under the contract to their detriment because of deception.
The key element is reliance on a misrepresentation.

We want people to tell the truth, obviously, but we also don’t want to litigate obvious hyperbole. It should be possible to describe something as “the best thing since sliced bread” without bringing in a whole team of UX researchers and bakery historians to calculate how well sliced bread was received and whether Tide Pods (or whatever) are a big enough improvement to meet that bar.
I think we do!
Possible for you, yes. But I think it's perfectly fine to have a different set of rules for different people based on incentives.
You could bring in a whole team of UX researchers, or a promo copy writer with slightly more originality than sliced white bread. Then they could make a claim or comparison that's trivial to verify. Instead of meaningless obvious (to most people) hyperbole.
You can't lie to people, and must have some evidence to back up any promotional claim made seems like a reasonable rule for people with a financial incentive to lie or be misleading to the possible detriment of others.
But if you're really so offended by such a rule, perhaps the solution is "these claims have not been evaluated by [trade industry group] and this product is not intended to treat or cure any disease, missing feature, required business need or other software bug!" Then you can lie as much as any snake oil salesman.
