OS: Which operating systems are support, what OSs you can use office suite on. Standalone application(s) (‘SA’) and/or Web-based (in web browser).
Rt: Runtime – here refer to if there is a standalone application variant (that is then downloaded and running locally, desktop) or web-based with a client-server architecture (web-browser being a (more or less thin) client).

1) MS Word, MS Excel, MS PowerPoint is primary focus here. There are other applications in different MS Office Suite packages of which some are also working on other platforms than MS Windows.
2) No standalone applications can be a lot bigger issue for some users than than others, for a few different reasons:
* Not necessary heavy office apps (‘Word/Excel/PowerPoint’) users but anyone that is writing documents, doing calculations / retrieving data in spreadsheets, maybe also working on presentation(s) at the same time, and getting information from various web-based resources, thus continuously  jumping in between applications (command-tab and command-shift-tab on macOS, alt-tab and alt-shift-tab on MS Windows, and correspondingly in Linux).
Very different workflow, process, or jumping between apps versus jumping in between many different web browser windows!
* Degree and easiness of working off-line, without access to Internet – both documents and software (like Docs, Sheets, and Slides from Google)
