It really depends on what you are trying to do. SCORM
may not be what you want. or it may only be part of what you want. Most authoring tools won't import anything from word. Lectora does a pretty good job gathering PPT but does require some clean-up. I have heard Storyline/Articulate deals with PPT well, also. I would not encourage Captivate as the imports essentially create images (not accessible) and to edit or change, it is a serious pain. Moodle can host
ppt and word files. The question is what you want to do with them. If you want to track use, Moodle will report whether the doc has been opened. It can't track if someone actually read it, obviously. But you could put data from word into a Book and then embed H5P questions to test for comprehension. Or use lessons the same way.
If you are not already using an authoring software, you might try to figure out what you want to use the LMS for and what it can do before buying software. SCORM is kind of old tech, if you can avoid it, you might try. And this is coming from someone who uses/creates SCORM all the time.
