Kinda. The MS 365 subscription can be ordered from the app store. I don't know about installing the Office applications afterwards, whether they then can be installed from the store.
Just putting their own games on the platform would be money down the drain
If they heavily rely on some frameworks very much tied to x86 Windows that required massive efforts to port, sure, but usually they don't for the simple fact that video game consoles and smartphones exist. Microsoft very much supports gaming on ARM platforms, most notably Nintendo Switch. There is no reason why Doom I+II isn't officially available for Windows ARM.
Moving over to another proprietary location data hoarder is not really a good solution, though.
Location Data. We collect location data such as information about your device's location, which can be either precise or imprecise. How much information we collect depends on the type and settings of the device you use to access the Services. For example, we may use GPS and other technologies to collect geolocation data that tells us your current location (based on your IP address). You can opt out of allowing us to collect this information either by refusing access to the information or by disabling your Location setting on your device. However, if you choose to opt out, you may not be able to use certain aspects of the Services.
Gaming on ARM is going to have a steep hill to climb until there’s a Proton-esque compatibility layer.
Or even better: The company developing Windows on ARM, selling ARM Surface devices, one of the biggest game publishers after the takeover of Activision could just release their own freaking games on their own platform. Not even the casual games are:
Lol, finally someone noticed that Windows on ARM exists. Microsoft certainly doesn't even though some Surface tablets are using it. Not a single Microsoft game has been ported to Windows on ARM.
It's not like the games are cheaper on other stores with lower cuts. Why would customers care if the lower cut just results in publishers pocketing higher profits.
This is by a Apple fanboy who is disgruntled that Valve broke up with Macs (Steam is still available but updates like the HL1 remaster aren't any longer). Yeah, send thoughts an prayers for a cult who buy overpriced computers with weak iGPUs that only recently learned to do some raytracing but understand no Vulkan or somewhat modern OpenGL.
Apple has decided that gaming on Macs is about iPhone games on bigger screens and not about supporting cross-platform APIs and frameworks. Don't blame any but Apple that your beloved platform is shit for gaming.

This is a lame ass video
