CC BY 4.0 is Creative Commons’ most permissive licence that still requires attribution. Anyone may share, remix, adapt, and build on the material for any purpose, including commercial, provided they give appropriate credit, link to the licence, and indicate if changes were made.

It is a good default for text, images, video, and datasets when you want the widest possible reuse but still want recognition. For pure databases in the EU, ODbL-1.0 addresses sui generis rights CC BY does not fully cover.

CC BY-SA 4.0 is the copyleft Creative Commons licence. Anyone may share, remix, adapt, and build on the material for any purpose, including commercial, provided they give appropriate credit and license their adaptations under the same licence or a CC-approved compatible licence.

It is the right choice for content that should stay in the commons even as it is remixed. Wikipedia uses CC BY-SA 4.0 in combination with the GNU Free Documentation License.
