I have moved a lot of our company to LibreOffice, and were starting to push web clients for software vs thin clients, so it can be run from mobile, Apple, and Linux. I only have 2 Linux Mint PCs out in the wild for more savvy users and no issues so far either. The EDR works on multiple OSes which is nice, so still compliant.
The other nice thing I've seen Lenovo and Dell offer are PCs that come preloaded with Linux like Ubuntu iirc, slightly cheaper too.
Power users still on Excel and MS Office for features, troubleshooting, and familiarity, but so far, much smoother than anticipated. Just need to convince the powers that be to roll out more Mint!
You're not stupid, you just need to learn done telltale signs. Most the time, for me, it's post history.
