Less is usually made of the paper and print developer choice for the following reasons:

1. You've usually only got one chance to make a negative, while you can print it as many times as you wish, with as many different papers or paper developers as you want depending on the look, print color etc you are after.

2. Related to (1), often much of the control work at the printing stage is during exposure (under the the enlarger) rather than altering things like contrast with print development. This is an oversimplification of course, but generally you have less control over contrast in print development than you do in negative development. Development can make a big difference in negative contrast, so that is the process you really have to get nailed down if you want to be sure you always have the information you want in the negative. The print is an interpretation of the negative so you have more flexibility to try different things without risk.

3. The negative is (usually) being enlarged. The print is not. So in choosing your film and film developer decisions have to be made about things like sharpness and graininess, which will show in the print as the image is enlarged. In addition, how you use your particular film developer can also affect these things (development time, temperature, agitation etc). The print is the final stage and the paper is not enlarged. So things like grain and sharpness in the paper do not really matter. From that perspective there is no point in arguing over something like whether say Ilford MGIV paper is grainier than another paper, or whether Dektol is a grainier paper developer than LPD. It is a non issue, whereas with films and film developers there can be big differences.

Paper choice should not be taken lightly though, of course. Different papers can have very different looks. Gradation can be different, as well as print color (paper tint, emulsion characteristics). Then there are other qualities to consider, like how different papers respond to various toning processes. They are often very different. The choice of paper developer has an impact on these qualities as well. But again, you have the option of playing around with different papers and print developers for any given negative. You can only make the negative once.
