Regarding this thread:
o Startup Apps
https://alt.comp.os.windows-10.narkive.com/nBlUljsT/startup-apps

That is interesting information about if there isn't that option:
o https://support.microsoft.com/en-us/windows/add-an-app-to-run-automatically-at-startup-in-windows-10-150da165-dcd9-7230-517b-cf3c295d89dd

I don't use _any_ of what you call "MS Store type apps", I don't think.
o But can we not create a "shortcut" pointing to them?

If they do have a shortcut, can't one put a shortcut into a startup folder?
o Win+R shell:startup

That is, can't one put a shortcut to a MS Store type app in here?
o Win+R %appdata%\Microsoft\Windows\Start Menu\Programs\Startup

I do that, for example, to enable both versions of Microsoft Edge
coexisting, as shown in this thread which contains the details:
o Tutorial to set up 3 Microsoft web browsers (Edge UWB, new Edge, & Internet Explorer) to work concurrently coexisting peacefully even after subsequent Windows Updates
https://groups.google.com/forum/#!topic/alt.comp.microsoft.windows/hUAf1lnum3E

And, of course, we did that numerous times with batch commands, as shown in
this thread which contains the details on how to create that batch command:
o Efficient Windows Admin command prompt of any color in any desired location
https://groups.google.com/forum/#!topic/microsoft.public.windowsxp.general/8VZQJyKeAvE

And, also with the task scheduler, which is shown in this thread.
o Expert help requested for removing UAC user account control task scheduler syntax
https://groups.google.com/forum/#!topic/alt.comp.microsoft.windows/7wpgdNscZNA

Or maybe simply by calling out a command in the AppPaths key on startup?
o What Windwos freeware adds powerful "phone Susan" & "vipw" commands?

Given I don't even have a MS Store account, I don't know if I can test it
for the OP. Is there a "default" MS Store type app (maybe Edge?) that we
can make a shortcut to in order to test this out for the OP?

In summary though, wouldn't one or more of the following work for the OP?
1. Possibly put a shortcut to the MS Store app "Your Phone" in Startup?
2. If not, possibly use the Task Scheduler, batch command, or AppPaths key?
