First, thanks a lot for your response!
Have you tried the standard way of reindexing Spotlight:
Making sure to drag the entire “Macintosh HD” volume to the Privacy window?
> Yes, I already tried to rebuild the spotlight exactly as explained in the link, several times.
After this step, there also indeed was a process of "indexing" going on, which also seemed to finish regularly after some time.
But that changed nothing.
Another valid question. How long has this been happening?
The issue of showing "0 results" in all apps persists since weeks regardless what I tried to do.
If you enter these commands in succession, any results, (such as “Indexing disabled/enabled”)?
No, when I enter any of these commands, the Terminal replied with: Nothing. Also no "indexing disabled" or similar.
Are there just no results at all when searching Notes and Mail, etc.?
> Yes, there are always "0 results" inside each app.
Yet, the Spotlight-Search using CMD + SPACE does work.
ADDITION:
Also a weird behaviour of my MacBook:
When I use CMD + SPACE and Type in trackpad or keychain access or anything else I would usually find in System Controls, it returns no matching results. Don't know if this is related, but - although rather minor - this part of Spotlight definitely seems to be broken, too.

UPDATE:
As I was unsure if there will be any solution for this problem, I just recently did a full reset of the whole Mac (deleted the whole disk and reinstalled a fresh Big Sur via the Recovery Tool).
Now:
- Spotlight works again as intended (via CMD + SPACE and in apps like Mail or Notes), but
- Typing mdutil -s in the Terminal still does not lead to any Terminal output (see attached screenshot).
As the latter behaviour still seems to be wrong, I'm still wondering if this problem is fixed, now - or if it's a matter of time until it's occurring again.
I'll keep this thread updated in case of any (bad) news.
If any ideas arise regarding why this issue was and why mdutil still does not work, even on a fresh Big Sur install, I'd still be super curious about it! :)
