A lot of bits and pieces on the tsdz2 in many places - couldn't find answer to: (clarify -- 48V , 500W "newer" model, B)
This thread on this site is the only comprehensive place I've ever found on the web. And, all the answers to your questions are already somewhere in this thread... When I first found this thread it was just over a year old with 16 pages and around 300 comments, as I recall, and I read every comment. Since then, it has exploded! While reading it all may be impractical for many today, you can search just this thread by using the search tools on ES.

- is the max cadence that the motor will assist the ~78 rpm? And is there a way to change that upper limit? I may have read that this ramps down to 0% assist between perhaps 78 and 100?
Nobody has ever suggested at "cadence" of that number that I can recall. Instead, the motor has a maximum RPM of 4000. Due to its own internal reduction gearing this works out to about 90 pedal-RPM. When the motor is beyond its RPM, you simply don't get any assistance, but you CAN pedal it faster, if you are able.
The TSDZ2 doesn't do "cadence" like the Bafang models.
There is a speed limit that has nothing to do with cadence. I have two units and I have turned it off on both of them without trouble, but I do not know if this is possible on all units since some countries have maximum speed limits and I think that's why it has the speed limit feature. So MAYBE depending on where you live, you can't un-set it, I don't know, but you CAN lie to it about tire diameter, number of magnets used on the sensor, or just disconnect the speed sensor.

- I think there's been a video posting that you can remove the top limit speed via the LCD controller menus -- correct? (it was in italian)
Maybe, IDK, I don't watch videos often.

- is there a feeling if the efficiency for this is really significantly lower compared to the BBS02? (percentage of electrical watts in that gets converted into mechanical watts out)
Anyone who suggest that is either an idiot or a propagandist for the BBS series. Owner reports found in this thread ALL say the TSDZ2 is VASTLY more efficient, and they back it up with numbers. ... I've never owned a BBS unit, so can't say myself. What I can say is that my 12.something Ah battery is good to around 100 miles, including hills, lots of stopping and starting and lots of high-speed. ...I once did 22 miles up (and down) some of the steepest hills in the San Francisco Bay Area and only used about 25% of the pack. My interpretation of driver reports is that the BSS02 series can't touch that kind of performance.

- are we seeing high mileage customers? I think BBS02s are having no issues normally for at least 10,000 miles.
The TSDZ2 isn't that old yet, but there are reports in this thread of people having over 3000 miles, as I recall.
