That’s the main way it’s used, but there’s no limitation to use it in another way.

There are some styles suited for modern day maps. Or historical maps, such as the April issue of this annual:

And with Cosmographer and a few annual issues included, there’s plenty of SciFi styles to choose.

They have a YouTube channel where they stream a mapmaking session, you get to see quite a few styles:

I do use it myself for SciFi (mostly for Traveller) and I like it. Of course, the number of available styles is not as overwhelming as the ones available for fantasy, but there are some good options.

One thing worth noting: for Sci-Fi you definitely want the highest tier, which includes Cosmographer and all the annuals.

The page for Cosmographer shows a few styles: https://www.profantasy.com/products/cos3_examples.asp

And here’s a few deckplan exampless on a classic Traveller style: https://www.profantasy.com/products/cos3_deckplans.asp

As for the annuals, there’s this post on the forum with a small screenshot/thumbnail for each issue in most annuals: https://forum.profantasy.com/discussion/10366/cartographers-annual-all-the-issues-linked-in-one-place

Finally, there’s this Youtube Playlist with a few of the mapping sessions that focused on Sci-Fi styles: https://youtube.com/playlist?list=PLrFvDl9qgYgsCVt58a41H3rcDjsAc4P4h
