I think that you will find that the 1:350 scale Tam Fletcher is the only WWII era, non-Japanese, destroyer available in styrene. There are modern destroyers (Spruances, Burkes, and soon to be a Kidd) and Aegis cruisers available in 1:350 scale styrene.
So, how large do you want to go?
Mirage is supposed to be coming out with some 1:400 scale styrene US 4-pipe destroyers. Look for them around the end off the year. As to whether there will be PE which is available from Mirage or another aftermarket supplier is an unknown. These kits will make up to be about 8 inches long.
Bluejacket Ship Crafters make an excellent destroyer escort John Roberts in 1:192 scale. It is wood with white metal details. It makes into an excellent kit. Thet also do a Fletcher. Fletchers served in both the Atlantic & Pacific, but were designed for the Pacific - where they saw most of their action.
Both Classic Warships and Iron Shipwright make some 1:192 scale destroyers. The Classic is a Sims class and the ISW kit is a Fletcher. Both are resin & brass.
Lindberg makes something which purports to be a Fletcher in their Blue Devil destroyer. Before you get a burr up your butt to do that one be sure to read Jeff Herne's article on SteelNavy titled 'Trial by Ordeal'.

It documents Jeff's efforts to correct some of the many flaws in the kit.
While a resin kit may look to be a large initial outlay of cash, you need to consider the total package price of what you get int he kit versus what you need to buy aftermarket. Prices become comparable.
By the time you buy the 30 dollar Fletcher, add another 30 dollars for PE, and another 30 dollars to replace the guns with ones with detail which approximate that which comes with many resin kits you are in the ballpark price for a Yankee Modelworks, Iron Shipwright, or White Ensign Models destroyer.
