Hi Chris,
welcome to this list and thanks for sharing your experience from using
LibreOffice with NVDA. My comments on the aspects you mention are inline
below.

the case if I use Control+Shift+Space toSelect all, all cells are copied to the
clipboard but NVDA announcesNo Selectionwhen I press Control+c.
On Windows, there are 2 different technologies that applications can use
to implement accessibility: UIA (User Interface Automation) and MSAA
(Microsoft Active Accessibility).
Microsoft Office uses UIA, while LibreOffice uses MSAA.
From what I can see, Excel triggers a UIA notification event after
finishing the copy operation and NVDA speaks "Copy" as a consequence.
I'm not aware of any equivalent in MSAA, so I think the reason why Excel
announces something while LibreOffice does not is basically that the two
applications are using different technologies to implement accessibility.
At least from a technical perspective, that looks OK to me.
The most annoying issue is how NVDA voices numbers. I formatted a column as
Currency, 2 decimal places, currency symbol £ and leading minus signs on
negative numbers. NVDA does not voice the currency symbol at all, even with
symbol verbosity set toAlland trailing zeroes on the fractional side of the
decimal point are truncated.
That's actually something that should be improved, and there is already
a report for this in LibreOffice's issue tracking system, Bugzilla:
