If I choose Times Roman for roman font, what font I must to choose for sans serif font If I want to obtain an aesthetically coherent aspect?
Times is a font designed for newspapers (New York Times). Its glyphs are therefore thinner with less space between them. When you want to write a book, I could therefore not recommend Times as font.
To get "aesthetically coherent aspect" for all 3 font types, the best is to use the corresponding Latin Modern font.
The same for Bookman font.
It depends on your taste what is aesthetically coherent. Just play a bit with the available fonts.
