Have you tried Ramda for the data manipulation functions you miss from Clojure? It used to not work very well with Typescript (lots of inference issues), but now it's gotten quite good. You can use something like https://github.com/vriad/zod https://github.com/vriad/zod to get both runtime validation and static types (via inference) at the same time. The downside is defining your types in a DSL instead of plain TS, but I think it's worth it for the runtime validation. It probably depends on your project, but I find type checking to be at least as crucial on the backend as the frontend (probably moreso), and being able to share types/have editor auto-complete across the whole stack is a godsend. While node isn't my favorite backend environment, it's not too bad (async/await are fantastic for io), and code sharing/type sharing makes it the most productive choice overall imho, all things considered. Clojure's a lot of fun though, and it has taught me a lot, so I do see where you're coming from!
