photos exported from Adobe Lightroom with an sRGB colour profile.
sRGB is not CMYK.
Photos should be CMYK to see color more accurately for print production. Chances are if you were to open a photo and merely convert it to CMYK, you'll see the same "dull" blacks. (And you can then adjust the photo for the desired CMYK output.)
What is happening with Proof ...
Could be that they are in the Master Pages?
On your right hand-side, there is your "Pages" menu. On top you can find the Master Pages.
Double click on Master A, and you'll be able to edit the number pages.
If the text should only be white you could use the effects-panel.
select the textframe you want to have white, go to effects and change the transparency of the text to negative multiplication. If you want to have the inverted color you could also use difference (but it's not that readable).
I'm afraid, I couldn't find a way to give it a specific color but ...
I will weigh on on this one as books, manuals etc have been and are my bread-and-butter in many ways, as I'm (amongst other things) a technical writer.
For what you're proposing, I'd look at DTP tools like Affinity Publisher or Adobe InDesign as my first choices.
FWIW, I've been an Adobe Suite user for decades, but have actively been transitioning to ...
FrameMaker is specifically designed for things like manuals and text books. It has more robust cross-referencing, indexing, etc. needed for such projects. That's the entire point behind FrameMaker.
While I have not directly worked with FrameMaker, I would be inclined to download the trial and try it. FrameMaker would be the next logical step if the InDesign ...

The characteristic lower "B" bow is there very close to your banana-word.
In your sample image the designer may have distorted the letters to get a "narrow type".

There are two full-spread page masters in this template, and the B-Master is the one applied to all the internal pages, containing the page numbering square - once you have that page master onscreen, you can change the colour of the underlying square quite easily.
hope that helps.
You can achieve this with a "marking subexpression", which are just () parenthesis where each set can be referenced later with $#.
So the below GREP finds three groups of characters, then rearranges them:
The 1st group finds anything up to the bracketed text, the 2nd is your bracketed text, and the 3rd ...
Probably not. Baseline shift works in your current unit of measurement, points, millimeters, etc. It does that because the Baseline grid itself is defined in 'pt' or 'mm', and not in percentages. However, you can do the math with a calculator and find out what percentage you need, also, if you type in '1 pt' in the box, then go back and type in 400%, see ...
Editing a font is possible in font editor software. There are many of them available commercially and for free. There are a few problems:
others do not have the modified font file, so they cannot print nor watch your documents which use that font (except if you have rasterized or outlined the texts or the font file is embedded) The document will be shown ...
Did you try Updating All Numbers from the Book panel popup menu?
Go to the Indesign Preferences and check if General → Page Numbering is set to Section Numbering instead Absolute Numbering.
Then Update All Numbers.
