[Gradient Overlay with no color]

You can also use a regular Pixel layer for this,

Yes but a gradient on a pixel layer is destructive
A fill layer can be made resizeable by creating a marquee first so
<ctrl>A
Layer/New Fill layer
Create gradient
allows flexibility for editing further

[Populating text boxes from a Master Data source (Not Merge)]

The next best idea I have is data merge into a table on a single page - is that possible?

Certainly
The zip file contains a spreadsheet and an afpub file
The spreadsheet has 3 sheets, ignore the first
The afpub file uses sheet 1page which is pretty horrible to read
An alternative if you're using Excel is to create the data like the transposed sheet then copy/Paste special - Transpose onto another sheet which APub can understand as it needs the fieldnames on the top row. As you're producing one table the spreadsheet will only have 2 rows. I have put the Table column headings as data but it's probably simpler to type them into the top row of the APub table

[Black and white and color negatives]

It appears there is no option to invert the negatives from Develop Persona,

It can be done with the tone curve but I don't think it's worth doing anything in Develop apart from applying the lens correction
By doing it all in Photo persona either the curves layer build can be saved as a macro or else a LUT can be exported and applied to RAW files as a batch job cos doing these one at a time would drive most people nuts. Here's a LUT to play with

[Opening encrypted PDF files]

I just downloaded a couple of files which opened fine in Chrome so I used Ghostscript on them and now they open in Publisher

command is gswin64 -dSAFER -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -sOutputFile=mine.pdf AQA-73671-QP-NOV21.PDF
or put this
for %%i in (*.pdf) do (
  gswin64 -dSAFER -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -sOutputFile=.\out\%%i %%i
)

in a Windows bat file to process a directory and output to a sub-directory named out which you'll have to make yourself
This is for five files
start 12:27:34.77
end 12:27:38.38
so not too shabby

[Data Merge from formatted excel data]

When I  merge data in Publisher, it shows the format code, not the number.

If you have a list of 'phone numbers like:
 13334444 - code 1 for Budapest
523334444 - code 52 for Debrecen
then the cell format 06-##-###-####
will display them as
06-1-333-4444
06-52-333-4444
in Excel
If you use an xlsx file with Data Merge it will all go wrong but if you use csv then it is fine

Sorry if I misunderstood
