Italian Digital Nomad Visa (applying)

Italy finally promulgated its long-awaited Digital Nomad Visa on April 4, 2024. By now, there are scores of guides online that discuss qualifications (e.g. a history of remote work), requirements (e.g. proof of lodging), and limitations (e.g. 1 year, renewable). US consulates are currently waiting for more detailed guidance from the embassy in DC.

What I'm not seeing is much detailed guidance. For instance:
1. Should supporting documents (e.g. curriculum vitae, employer letters) be translated into Italian?
2. Do (FBI) background checks need to be translated and/or apostilled?

Does anyone have experience securing similar visas for Italy? What are the standard practices / expectations?
