Maybe there are shortcuts, but I use

nix-env -qsP \*

to get a list of installed stuff in my profile and then copy paste
that into a line like this:

nix-env -e package1 package2 ...

I think in general you can choose yourself what to install with
nix-env and what to put in environment.systemPackages. I usually start
by installing a package with nix-env, and if I find it useful to keep
for later, I move it over to systemPackages.

About the "in general", I've heard about issues with some KDE programs
when they are installed with nix-env and not in systemPackages.
