Avoid using "populate a word document" connector in my flow

Question

I currently have a Power Automate App that takes text and images and patches them into a SharePoint list. My original power automate flow triggered when a new item in the SharePoint list is created. It then initializes variables to convert the pictures properly. Next it populates a word document (premium feature) and finally creates a file in SharePoint.

Is there any good substitute for populating a word document since it is a premium connector? I've seen a few videos that suggest get file content, create file, update file properties, and get file content. These often require creating a new content type on SharePoint. However, they don't show how to get text/images from a power app into the new content type. Is there anyway to take the content from the SharePoint list and plug it in to some sort of file?
