Hey WC,
I dont know of a particular resource that will show you exactly what i do but there are loads of great resources out there. YouTube has been especially helpful on my journey..
i'm not an expert, i'm still finding my way, but i'll try to explain how i do it, with images. Again, this is for Cloud rather than PAD.
Here is my nice excel form formatted for humans to fill in. Lots of cells everywhere, not in a table, not easily digestible by Power Automate

Here is sheet 2 in the spreadsheet. I've created a single line table with an id column containing 1 and the other cells are just =Cell from front sheet.

Now we can use Excel 'Get Row' to get this one row but before we do that we need to setup our word template!

On the developer tab (you may need to enable this in settings) there are content controls us the Aa one highlighted to add a content box that power automate will be able to see. use the properties button to give each content box a name.
Now finally on to the flow.

For the get row connector we navigate to where our excel file is stored, the key column is the 'ID' column we set up and populated with 1. the key is 1. Now use the populate MS word template connector and again navigate to where your word template is stored. you will see all the content control boxes you added to the word template. you can see that the excel fields from your table can now be inserted to the right places in your word doc.
After that you can 'Create File' or convert to pdf or whatever else you want to do.
Hope this helps
