Well my company provides subscriptions of Lynda, Safari, Books24x7 and many other third party content for learning.
Out of all Safari is what i prefer over all. It has all major ebooks from Willey, and other top technical publishers.
Apart from eBooks, there are tons of other video courses, complete video based learning paths for React, AWS, etc ..
PS : Lynda has pretty basic content on topics. If you want to know something more than average about the technology Lynda is not the place for you.
PPS : I prefer SAFARI BOOKS ONLINE safaribooksonline.com over Lynda, Books24x7, Plural-sight. Safari also have all the conference/training videos from O'Reilly Media Conferences oreilly.com/conferences , FrontEnd masters and many others.
Courses from Udacity are good but, very limited. Never used egghead.io extensively.
