Another lawyer here. I've been successfully running Ubuntu for my practice for the past five years. Currently on 21.10. Crossover Office takes care of the Word problem but I mostly use LibreOffice. Word is useful for appellate briefs and Table of Authorities. For Crossover, I need to be in X11, not Wayland. Otherwise, it's entirely boring and seamless. Brother ADS-1700W scanner works with Document Scanner. Thunderbird 91 is great for encrypted email. It's really not an inconvenience to use Ubuntu in an office.
Edit: Document Scanner not Scan.
