Hello @Lotfi Ounis ,
Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.
I understand that you would like to know what the Frontend host equivalent for Front Door Standard is.
For Front Door Standard/Premium, the frontend host is accessed by its endpoint hostname.
Refer: https://learn.microsoft.com/en-us/azure/frontdoor/create-front-door-portal#verify-azure-front-door
https://learn.microsoft.com/en-us/azure/frontdoor/endpoint?tabs=azurecli
When you migrate your Azure Front Door (classic) to Azure Front Door Standard or Premium, the Frontend/domains changes to Domains (Copied from Front Door (classic) profile).
Refer: https://learn.microsoft.com/en-us/azure/frontdoor/tier-mapping
You can find it under properties in the Overview page or in the Front Door manager page under domains as below:
