What Adobe Stock 'Audio license' is required for use in a video NFT for sale?

This looks to me similar to selling posters, T-shirts or mugs with assets printed on. You need to ask yourself what the primary value of the asset is. If the Audio is only an auxiliary asset to your creation, it may be enough with a standard licence. Nobody can, without knowledge of the exact project, give you a definite answer, especially that we don't give legal advice here.

(Disclaimer: As always with licensing, this is my interpretation of the rules. I think they are correct and advice is based on reading and interpreting the licence terms and on fair use for both the buyer and the artist/stock company, but I cannot rule out that my interpretation is wrong. I'm not an Adobe employee).
