The biggest benefit that I've found for jQuery (and a lot of JS libraries) over vanilla is browser compatibility. I generally don't have time to check compatibility of every mildly complex piece of JS I write. Using a library often solves that issue

That was a relevant answer couple of years ago. These days you can achieve most with having a properly setup IDE-intellisense ( e.g. WebStorm ).
Does that really solve the issue though? All the IDE can tell you is that some browser version doesn't support what you're doing, it doesn't write the polyfill for you.
Most of the polyfills these days are pretty much syntax sugar & ES6 transpiling. If you do your code in non ES6 plain JS way, I'm quite sure the IDE will give you the benefits that you receive with jQuery.
By "these days" do you mean "needed to support the latest version of each major browser"?
