Let's say I write some JS widgets and want to reuse them on multiple sites. What kind of license do you recommend? It's not open source, but is there a good boilerplate for this kind of thing? Or a question-tree like GitHub's pick an open source license, but for non-open source?

Don't mess with licenses. Just keep the copyright with the code in the project. They have your permission to use the widget (implied license, basically), so they're in the clear, but they won't be able to distribute it beyond what you've allowed, legally.

Not an expert, but going back to basics you only license things you own. So if they will retain the IP you don't license anything.
