Lol what!?As long as 5E classifies all PC races as Medium creature, then no, they should all be average. If you want your Goliaths that are working on the loading docks to be stronger to show that, then give them a boost in strength. But the average Goliath walking down the street, who is an unstatted NPC, should be just as average in stats as a human or dwarf or halfling.
Please extrapolate your reasoning, because there is no obvious link from “both medium sized humanoids” to “same basic musculature, skeletal structure, etc”.
Humans, chimps, and gorillas, are all medium humanoids, too. Definitely a difference in average strength.
