I think it’s a “use the right tool for the job” thing. Putting ephemeral information like session info in URLs sucks and should only be done if you need to pass it in a get request from a non-browser program or something, and even then I think you should redirect or rewrite the url or something after the initial request. But I think actual navigational data or some sort of state if it’s in the middle of an important action is acceptable.

But if you really just want your users to be able to hit refresh and not have their state change for non-navigational stuff like field contents or whatever, unless you have a really clear use case where you need to maintain state while switching devices and don’t want to do in server-side, local storage seems like the idiomatic choice.
