I agree, Web3 is a buzzword with little meaning. The features I am most looking forward to are: 1. Self-owned storage. I would love it if I could make and use apps where the users owned the storage (in a convenient way). This means that running apps is basically free and you don't have the legal pain of controlling user data. It also means that users can export their data (the just need to figure out how to interpret it). 2. Decentralized hosting. I think it would be amazing if you could keep using sites even if the original host went offline. IPFS is making good strides here. For example if you like my first player chooser you can pin /ipfs/QmWBUag1ynHaZekVHyr1VfMgF6fh64PPP46oiNYCgCPCQK and use it forever. This combined with 1 means that you can keep using apps without any creator involvement. These two feel so close that they could be used today. There are efforts, but at least for 1 not much is really sticking. The above 2 are all about single-user data though. Combining data for multiple users like many of your other points reference would be super cool but is a much harder problem, particularly around security and privacy. I think that will be full "Web3" but I see us as a long way off.
