Honestly, I am yet to find a true value-delivering project in the Web3 space. The twitter founders "Web5" proposal sounds kind of interesting though (even though I don't really like the name).
The tech is valuable and some pretty cool innovation is happening. It's like the early days of any tech. The products with huge impact will take time but will happen. Polygon ID with ZKP which just got released for instance is taking id verification to a new level. As a developer and builder, imho, it's a great time to invest in web3.
