Hi @Audi86 ,
Per my research, we are unable to copy page with web part as a template. There is no such function in powershell currently. As a workaround we can get sharepoint web part alone by Get-PnPWebPartXml.
Get-PnPWebPartXml -ServerRelativePageUrl "/sites/demo/sitepages/home.aspx" -Identity a2875399-d6ff-43a0-96da-be6ae5875f82
Here is more details in the document
