PnP Deploy Template to existing Multiple Sharepoint Site Collections
Applying templates with PnP PowerShell/Core can indeed be a slow process. I have however found some ways to speed things up.
First of all I don't like the concept of Content type hubs, however the use of a content type hub could speed your process up a bit. You would only need to apply fields and content types to the conten type hub and then you ould exclude them form the rest of your template applications.
The other option is to exclude handlers from your template application. So if for example you know that you have made only chnages to fields. Then run:
Apply-PnPProvisioningTemplate -Handler Fields ...
(or if you are running the core libraries you could run only the fields handler there). I would still extract the full template but only apply parts of the template to your many sites. Of course you do need to be very much aware of your chnages that you want to apply.
