I admit I have not used GraphQL in Clojurescript. However, Clojure has its own type-system. Of course, purists would argue that Clojure.spec cannot be categorized as a type system, albeit it is, and you can do pretty cool things with it.
For example, you can build a suite of specs that denote a ledger - where amounts in every transaction depend on each other. That is not a trivial task - most other type-systems don't give you good instruments to achieve something like that.
You can then use those specs to generate data for property-based tests.
You can also use them to validate the data flow in the back-end for different data stores. And re-use the same specs on the front-end for input validation. Clojure and Clojurescript allow you to get as much code-reuse as possible (even though the code has to run in completely different environments).

Perhaps you haven't had to build reasonably complex front-end applications, where a user has to go through many steps in the UI. With a lot of state and state transitions involved. I spent several years building web-front ends. Used if not all, but most popular ways to compile/transpile/deal with Javascript. I'd choose Clojurescript, because it makes sense for me today.
Tomorrow perhaps something better comes up. But Typescript today is not an option for me. I have tried it multiple times in multiple projects. "Joy of Typescript" doesn't even sound right. "Joy of Clojure" though is a thing. People love Clojure and Clojurescript, and not without good reasons.
