Teams is unreliable on every platform (having used it for years on Linux, Mac, Win). Would recommend against it.
Clearing documents metadata in Libreoffice, yes. It existed as far back as 7 years ago when I was running my own company, and my lawyers and I would be exchanging documents with potential investors.
This said, I also (when needed) run windows 10 in a kvm window, with Office installed, when libreoffice, or office365 is simply inadequate. This is ... rare. I mostly boot the kvm to patch it these days. Haven't needed its capabilities in at least a year (then again, I am not a lawyer).
Dongles (yubi-key, etc) all work great on Linux/Mac. YMMV though, if they aren't common systems. Again, you can run windows on a VM, and pass through that specific port (USB, etc.). It works, though sometimes the software is buggy so that it sends a reset, and you have to unplug/replug the dongle. This is from my Yubi-key experience on my windows kvm running on my linux laptop.
