Well if you were running GWX I could help out, but I'm unfamiliar with NYGM, so I don't know which mods are compatible with it.
If you go to the download section, try sorting them by number of downloads. The most popular will be on top then.
Usually, in the description you'll find if it's compatible. Otherwise there's usually a read-me included with that info.
Also, every once in a while a topic comes a long where people post a screenshot with a list of all the mods they are using. Try using the advanced search function to find these topics.
Are you looking for graphics mods? Gameplay? Sound? All of the above? Again, the advanced search tool is your friend. Helped me find a lot of good ones.
And there's a member here (Plissken 04 I believe) who keeps track of all the mods that are posted, and hosts them on his own server or something. They are sorted by the name of their authors however... So you have got to know the name of the mod author first. But it has literally got all the mods that were ever uploaded here I believe. Link:

Good luck.
*edit* Just read your first post mentioning the interface mods. Well there are a couple of different (and very good looking) options out there, but most tend to change a lot of your interface. And some of them require you to change the way you play a lot (that's not a bad thing; it just takes some getting used too). However I don't use them so I don't know all their names. Found these two though, they seem to be quite popular:

Maybe some one else can help out with more.
