FWIW, I've heard you can use Eagle chains on Shimano 12s chainrings and it works fine. Or Shimano 12s chains on any narrow-wide ring, if you use an Eagle quicklink. Supposedly. But I agree that it's a quagmire of conflicting "standards."
EDIT2: I say this because I spent a long while finding a 26t Shimano 12s chainring because I have baby legs, and I seriously considered trying the Eagle link/Shimano chain/Shimano cassette/Shimano derailleur combo. Turns out Garbaruk makes one though.
I would also look at Race Face Aeffect cranks, they come in 24mm spindle and will happily fit 30t rings; I have a 26t on mine.
EDIT: oops, took too long typing and Andrew beat me!
