Sometimes you don't even have UI alternative, only PowerShell. Much of Set-AdfsProperties have no UI alternative. Workflow manager/Service Bus on prem configurations. Office online configuration. SharePoint particular configuration (i.e connecting to workflow manager). WinRM things via powershell or alternative executable (like setting specitic certificate for TLS communication channel). Add-VpnConnectionRoute, ... I'v stumbled upon many and many "regular" things that can be configured only via powershell. But PowerShell for me is the best thing that has happened to Microsoft ecosystem.
