I have a fully cloud-based environment but recently had a requirement to set up a few servers on-premises. I want these machines to join the local Active Directory (AD) instead of Azure AD. What's the best option to have a single Additional Domain Controller (ADC) on-premises so that users and computers can use the local AD instead of AAD? Additionally, these servers require SMTP servers to send alerts.

You might want to verify that you really have to deploy on-premises servers. Instead, consider solutions such as Azure Arc.
But if you really have no choice, then refer to https://learn.microsoft.com/en-us/answers/questions/1044179/users-sync-from-azure-ad-to-onpremise-ad
