Nix also defaults new build commands to the equivalent of `./configure && make && make install` so it works out of the box with a lot of packages, as long as you declare the build inputs that it may need.

As for disk size, beyond garbage collection, you can also ask Nix to sweep its store and hardlink identical files together in order to save space if you suspect significant file duplication (and if your FS doesn't already deduplicate blocks).
