Idk about anything that has a cloud service because I just rawdoggit and use a USB cable to pass files between the phone and the computer, but if you don't give a gaf about that and just want a functional word processor I recommend Writer Plus for phone which I have been using since I was like 14, and Notepads for computer which I only found because the default Windows notepad doesn't have a dark mode.
Have I tried other options? No so take that as you will.
