Welcome, Zelenyj. There are many detailed books on various space hardware, if one digs around a little. Part of the reason sci-fi control panels in old TV shows are so sparse is because lights and buttons had to be big enough to show up on old TVs. Extreme detail also costs more.
Ultimately, futuristic controls will probably look cleaner and simpler, rather than more congested. An interface should never become an inyerface, to coin a term. (There are lots of books on the psychology and ergonomics of good interface design, too.)
The Thermians in GALAXY QUEST had no trouble fitting the necessary controls into the designs seen in the "historical documents."
