Any distro you’d like. Use the office / outlook stuff in a browser. I believe kde has a way to use onedrive in dolphin, though personally I would keep my data on my computer unless it is for a group project, just make sure it’s backed up. I’d also have a VM handy with the spice guest tools. It is good to have at least for when you have to hand your computer to someone who may be uncomfortable with linux. I would use debian on a school computer for the ludicrous stability, but use whatever floats your boat.
