What excites me most about Node upgrades are the introduction of new native Javascript capabilities, because of the underlying V8 upgrade. You can figure out what those capabilities are on this website: https://node.green/.

You have to scroll down all the way to "Node.js ES2021 Support" to start seeing features that work in Node 16 but not Node 14 (the current LTS version). Of course, it's possible to use Babel to bring those features into Node 14, but I enjoy leaving it out of my toolchain when possible.
