Between the three I'd go for Linux Mint. It was my first distro too, and it makes the setup process very easy, especially for users coming from Windows. Manjaro and Ubuntu are fine, plenty of people I know love them, but they've both made some decisions in recent years that I don't like. The former being negligent with security updates, and the latter forcing their own, worse, package manager on users. You shouldn't have any issues with Mint.
Most of the apps you mentioned are available for Linux, including Teams and VirtualBox, though you'll probably have to download those from their respective websites. Office 365 still works from a web browser, and you can open its documents locally with LibreOffice (though more complicated documents might have some formatting messed up). I haven't heard of uPlay, but there is an unofficial Linux client for Epic Games (called Heroic Launcher), and ~90% of Windows games either support Linux or work through a compatibility layer such as Proton.
I'd recommend using Fedora Workstation, it was a great experience back when I myself had an HP ENVY "fliptop". Anything with GNOME as its desktop environment should be perfect.
