I'd suggest simply dual-booting windows and your choice distro. You're going to be using Microsoft services either way, whether through the browser or native apps. Just use windows boot for school exclusively and have your onedrive and office there. and then personally use linux.

Microsoft pays extra attention to Ubuntu LTS and RHEL. Not my first choices, but in particular you'll see stuff like AAD auth on Azure VPN supported on Ubuntu LTS. There will also be some work going into proper Intune support, if that matters.

I would prefer Fedora or Debian for a more stable environment, and use Arch at home, but we have to keep interoperability in mind sometimes.

Another thing to look into, and I really hate to since Broadcom bought them, but you can run Windows inside VMWare, and use unity mode to break individual windows out into your DE. Beware of the new licensing.

Basically it doesn't matter if you can use the webapps.

Mint is the best traditional noobie distro, while I would suggest Silverblue, if you just want to use a robust system that requires far less maintenance effort than a traditional distribution with limitations that may are may not affect you at all.

I always go for Linux desktop at a job. Office 365 runs just fine in a browser. Not ideal, but MS will never give up teams to a Linux Installer again. They took down the 1 they had which wasn't great but still worked

As most others said, pretty much any distro is fine. You have a powerhouse of a laptop, so running a Windows VM inside of KVM would pose no problem, but if you can, I'd advise to try avoiding a VM.

Teams is basically just a web app masquerading as a classic application using Electron, so you can just use Teams inside of your browser of choice with minimal features missing (the only one I noticed was green-screen, but I didn't care that much about it).

Even if you use a lot of Office, you'd be surprised at how similar LibreOffice is to MS Office. The UI is a lot worse IMO, but 99% of the features are there. Tables in Word/Writer seem to behave quite a bit differently for one which can get annoying, along with the usual problems of switching from one UI to another. As for formats, LibreOffice supports MS Office extensions. There are some differences in rendering because of what I see as MS bullshit, but it's limited to padding, font size, etc. (and missing fonts), but if your teachers are open to it you can easily send them the original as well as a PDF reference just in case.

I didn't use Office web apps for a few years now, but when I did they were missing a lot of features (more than 80% i'd say), but others say the situation has improved, so you can try that in your browser of choice like Teams.

If you need the desktop Office apps, you maybe could use Wine or something to run them on Linux, but I don't have any experience with that so I don't know how well they behave or how the setup is.

You could easily run a VM with KVM with the specs you listed. Personally I find the installation of KVM and Windows VM creation a bit convoluted, but there are great tutorials availiable online and it's a one-time ordeal of maybe 15-45 minutes (including VM creation, depending on how fast you want to go/how familiar with the Linux command line you are), so not that bad. Utilizing virt-manager limits command line use to just the first setup of KVM. Installing the VM can be done graphically using virt-manager.

I don't know how drawing tablet passthrough compatibility in KVM is (probably great though). RedHat drivers enable shared clipboard and dragging files over between the host and VM, so even that should be quite painless if you choose to go the VM route.

Office 365 runs out of the box on Crossover.
