Sorry for my ignorance, I am a backend developer and I am trying to figure out what is the best for my frontend code (when I work alone on something). So far I was using Tachyons (https://tachyons.io/) and elm-ui (https://elm-ui.netlify.app/). Is there a chance that Tailwind would be better for small / medium sized projects than these? Based on your comment it looks like. The only problem with Tailwind just by looking at the default settings was its size. I was reading somewhere that you can greatly reduce that. Your second point sounds pretty good (almost like a discriminated union for CSS)
