D&D has lots of dragons that aren't chromatic or metallic. Not only do I love dragons, but I love weird and outrageous dragons. Like ones that breathe spiders.
I don't generally like pirate or nautical content. Songs of the Spellbound Sea for DnD 5e has made me reconsider that statement. It has everything I could want.
D&D isn't the only RPG out there. These are some of the best indie TTRPGs that you need to play as soon as possible, from small presses to individual creators.
With the Book of Magic and Arkand, Dragonbane RPG players will have not only a core set, adventure path, and bestiary, but also a full worldbook and magic core.
