Selecting license for personal professional site's content
For licensing personal content, you almost certainly want to either use one of the Creative Commons licenses or else declare your content All Rights Reserved.  There is actually not one, but seven Creative Commons licenses, which span a wide range of preferred usages (here is a handy tool for choosing a license to use), and the licenses are  well-maintained and highly compatible with themselves and others, even internationally and in complex remixes.

In general, then, if you want your content to be shareable, you should choose a Creative Commons license, and if you want it to not be shareable, your should declare it All Rights Reserved.  Alternate licenses for shareable contents are generally not as compatible, well-maintained, or well-understood by others as the Creative Commons family, and thus will generally be no better (and often worse) for sharing.  Alternate licenses for non-sharable content are generally intended to support particular commercialization relationships, and would be negotiated when such a relationship is being established.

Of this set of options, for a personal website, I would generally recommend CC-BY.  This is the most lightweight and flexible sharing arrangement, and thus generally allows the most potential for increased personal visibility (attribution is always required).  If you're planning to put up major works that you think others will want to publish commercially, then you might want to consider using All Rights Reserved for those works, but probably not for small works or for the web pages that contain them: at an early stage of your career, attention and credibility will be much more valuable than the largely non-existent possibility of some sort of royalties.
