You don't need to use an embedded font for the chapter headers. Let the user choose with his/her choice of font.

What's wrong with Times New Roman as a body typeface? It's legible at a moderate size (13pt or 14pt), and it is commonly available. About the only negative is that it might be considered a bit boring since it is so often used. I have considered Thorndale as an alternative. I also considered Georgia but dislike the way it renders numbers.

Times New Roman is not a good font to use as the body font. It don't work well on an eInk screen. Besides, a lot of people have their own preference of main font.

The reason I use Comic Sans is that I wanted a typeface that looks like handwriting without being too fancy, like many of the script-like typefaces that are so fancy that they are difficult to read.

There are lots of handwriting fonts that are not Comic Sans. Have a look here. There are many handwriting fonts. You'll be able to find something good. https://www.1001fonts.com/handwritten-fonts.html?page=1

For printed text or screen display I do use a monospace typeface. I chose Courier New because, like with Times New Roman, it is commonly available, legible at a moderate size, and it's appearance clearly indicates something printed.

By using your choice of Courier New, if could be too light for eInk. It would not be an issue if you fond a version of Courier that's dark enough.

I do use italics when showing thoughts. What I do is surround the thoughts with square parenthesis (using them just like I use quotation marks when rendering speech) and render the thoughts in italics.

When I see [some text], I expect that to be a link to an endnote/footnote. The text should make it obvious it's a thought and not the use of brackets.

When I make an ebook for my own use, I make it a PDF so everything needed to render the ebook is part of the file itself. I don't have to worry about which typefaces I have on my computer and/or e-reader, and it will appear on my e-reader exactly as intended.

Do you make the PDF for the screen size of your Reader? IMHO, you should make the eBook in a reflowable format. The reason being is that it won't matter the screen size. Also if you want to change the text size you can.
