Learning office may be a process of continuous exploration. In the process of continuous use, you may continue to learn new technologies due to various needs.
I cannot judge your current research progress on the office, nor can I judge the technical requirements of different companies to use the office.
I suggest that you can check the posts posted by other users in this forum and check the problems they encountered in actual use. This may be a good reference for you.
Mac and Windows versions of office are slightly different in use and functions, but they are both important. You can study the use of office on mac, but I also recommend that you also use office on windows.
Anyway, you can learn most of the office features in the links below, which includes all the office software so far:

If you encounter any problem in the process of using or researching, please feel free to post any ideal in this forum..
(From my personal point of view, to learn a new technology and find a job, the most important thing is patience and persistence. I believe you can do it. )
