In the 'Naruto adopted by a dragon fanfiction', the dragon could be a very old and wise creature. It sees Naruto's inner strength and decides to raise him as its own. Naruto gets to explore the dragon's lair which is filled with ancient treasures and knowledge.

Well, one possible plot could be that Naruto, being adopted by Madara, is trained in ancient and powerful Uchiha techniques from a very young age. This would make him an even more formidable ninja early on. He might also gain insights into the Uchiha's history and grudges, which could influence his views on the village and its politics.
If Naruto were adopted by Fugaku, he'd likely be exposed to the Uchiha's Sharingan secrets earlier. This could give him an edge in battles and a different perspective on his own powers. He might also face more political intrigue within the Uchiha clan. With Fugaku as his father figure, Naruto could become more reserved and calculating, rather than his usual impulsive self. His relationship with the village might also be different, as the Uchiha had some underlying tensions with the rest of Konoha.
One possible plot could be that Naruto gains a whole new family structure. Hiashi might train Naruto in the ways of the Hyuga clan, which could make Naruto an even more formidable ninja.

Well, one possibility is that Naruto would become an even stronger ninja faster. Jiraiya could train him more intensively from a younger age.

And Naruto would probably have less of the loneliness he felt in the original story, since Jiraiya would be a more present father figure.

This could lead to Naruto being more of a lone wolf type of ninja at first, but still with his strong will to protect the village.
