I shredded cardboard, soaked it for weeks and used it as mulch / groundcover over the winter for my garlic. The bed has never been as weed-free and the plants look quite healthy.
The soaked cardboard semi- dries out and forms a mat that doesn't blow away. It seem to be largely dry on top.
The garlic is pretty green and strong, haven't been feeding it lately, I did add chicken manure months ago.

Yup. I used some as “mulch” for a long row of hibiscus. Suprisingly few weeds
INB4 soak it in pee
when you used it as mulch, did it not blow away on windy days?
