I prefer nsfw to be reserved for nsfw plus it usually only blurs images on the clients I use. If it's a huge spoiler maybe have a few newlines between the warning and the content so it gets cut off in the preview.
If you mean for images I'm not sure but still think that the text warning is enough but it's not like the steam page doesn't give us a few glimpses with the updates anyway.
This seems good enough for me. I think I'd prefer the NSFW tag, but I can see that being an issue for folks who block NSFW tagged posts because they don't want to see nudity or gore.
