Can anyone confirm whether External Suitelets can still run Clientscript file using form.clientScriptFileId in 2024.2? I am running into issues with this (403 Forbidden error) when loading the External Suitelet externally (works fine internally). EDIT: Figured it out, turns out the Clientscript file need to be set to "Available without Login" explicitly now.

That's how it has always been as far as I know for externally available Suitelet.
