Great news and looking forward to how this goes. I still find it incredible that the frontend javascript ecosystem hasn't found a reliable and productive contender yet, a framework you could be sure would be still relevant without too much changes in 5+ years, something like what Ruby on Rails is for full-stack.

Some would say that React/NextJS has this role but I have to disagree. When using React/NextJS you still have to rely on third party library for routing, state management, querying etc. like React-Query, React-Router, Redux (Next has a router but you still need libraries to do the rest). Some of these libraries change a lot, some become less relevant, new libraries emerge, and in the end when you start a React project you must go through the "library shopping" step.
