It appears you have a problem that is more managerial in nature than
technical, that the best technical measures can do no more than
mitigate.

Scary. My employment was in a US DoD agency that was pretty careful
about information assurance generally, where such activity was forbidden
and punished if found. I do not like to think about having to make it
work.

I contacted a relative who does this routinely. Windows alternately, I
contacted a relative who does this routinely about the initial queston
about writing to NTFS file systems from Linux and Windows alternately.
Although he does this in a dual boot environment, and with either Ubuntu
or Mint, they should be similar enough to Debian and the proposed use to
be meaningful.

He did not report problems with NTFS as such, but mentioned possible
OneDrive sync issues and inability of Linux to write to a Windows drive
if it was closed down in a locked state. I knew nothing of such a
"locked state" and Google search for it indicated only issues that
suggest prior file system corruption that needed chkdsk or SFC (and
possibly bootrec, or even Windows refresh or reinstall), so probably not
a meaningful barrier.

Prior testing would be appropriate, with verification of the 90% or more
most common use cases, maybe with help of a relatively knowledgable user
or a few of them.
