I studied CompSci, so a very technical field, and with one exception (Power BI), everything I used ran on Linux just as well. For my Thesis, I used TeXStudio. For normal writing or presentations, I just used LibreOffice. For calculations, I used Python. For collaborative document editing, we used Google Docs.
Word of caution: LibreOffice supports the various formats of MS Office, but I’ve had issues the other way around, where a presentation I created in LO wouldn’t work in MSO. If you need to collab on files together, I’d recommend Google Docs. If it’s just you, I recommend sending PDF versions along with (or instead of) the original file, just to be sure.
