How best to share customer reports

I appreciate this may be slightly vague but I was hoping someone could point me in the right direction to the best way to share reports with customers.  I have considered the following options but none seem to fit all of the requirements.

• Share report manager
• Create SharePoint extranet
• Share Power BI dashboard
• Another option

Our requirements are as follows:

• We would need the customer to manage their own users
• We would need the reports to change language based on the user
• We would need the branding to change based on the user
• We would need the reports to be locked down based on user

Thanks Graham.
