Tried to figure out a list of some of my favorite licensed NES games earlier for no particular reason, and came up with:

• Super Mario Bros. 3

• Kirby's Adventure

• Wario's Woods (though I prefer it on SNES)

• M.C. Kids

• Little Nemo

• Cocoron

• Hatris

• Tetris 2 + Bombliss (mostly for Bombliss)

• Pipe Dream

• Rampart

• Bomberman II

Which tells me I'm really into platformers and puzzle games, and extra RAM is also pretty common among games I like (8 out of 11 of these) even if it's uncommon across the library as a whole.

I haven't explored the library a whole bunch though, so maybe there are games that'd become favorites if I tried them!
