For LaTeX documents like technical papers... Something like Palatino (or even Computer Modern Roman) for body text. But for headings, humble Helvetica looks good, and a bit less "academic". (I really dislike the default CMR at large point sizes.) For monospace bits, again I dislike the unusual-looking TeX default, so something serifed or otherwise clearly unambiguous (for "1" and "l", "0" and "O"), and thick enough to be legible (some Courier are too thin). Inline, at a slightly smaller point size than body text, to look proportional, and maybe a little smaller in code blocks. For a book, I was thinking something slightly flashier for headings, at least on chapters, maybe Linux Biolinum.
