I'm still struggling here so thanks for your patience.
First, I tried the ""plug it in after the upload starts" work around, with values of 'after' from about 1 to 4 seconds, but no joy. On some/all attempts I got this:
An error occurred while uploading the sketch
C:\Users\terry\AppData\Local\Arduino15\packages\ATTinyCore\tools\micronucleus\2.5-azd1b/micronucleus --no-ansi --run --timeout 60 C:\Users\terry\AppData\Local\Temp\arduino_build_71373/Blink.ino.hex
Please plug in the device (will time out in 60 seconds) ...
... and that was after plugging it in.
There were three other 'hits' listed when I filtered Boards Manager with 'tiny'.
This was the message at the bottom of the IDE window after loading the Blink sketch and choosing the board.
'37 ATtiny (Micronucleus, MH-ET t88 w/16MHz CLOCK), Enabled. 16 MHz (external 16MHz, USB). MH Tiny. B.0.D. Enabled (4.3V). Reset. Upgrade (via USB. fuses unchanged). Always. Enabled. PortA (pins 23—26)on COM5'
(I have not tried changing permutations of the 'parameters' offered there.)
"Since you have an ISP programmer, you could use the chip with no bootloader at all as well."
I assume you mean using a UNO as an ISP, which was how I described adding the bootloader? (I do also have a CH340 module which I don't think I've used for a year or so, if that's relevant?)
Should I at any stage be using one of these pogrammers, other than AVRISP mkll and Arduino as ISP? Those beginning with 'USBtiny...'? or 'Micronucleus'? If so, at what point in the obstacle course?

I have watched several videos and read a dozen or so threads/articles but so far not come up with a fix. You mentioned several; was there one you found that looked particularly relevant?
BTW, note that my chip is marked 'Tiny'; no mention of 'MH' or '88'.
Other messages I've seen at other stages:
avrdude: usbdev_open(): did not find any USB device "usb" (0x03eb:0x2104)
java.io.IOException: Cannot run program "C:\Users\terry\AppData\Local\Arduino15\packages\ATTinyCore\tools\micronucleus\2.5-azd1/launcher": CreateProcess error=2, The system cannot find the file specified
avrdude: ser_open(): can't open device "\.\COM5": The system cannot find the file specified.
Not sure if I tried the option 'ATtiny48/88 (No bootloader)' earlier, so maybe I'll solder up the six ISP pins on another of my Tiny chips and do so.
Finally, in case it offers any clues, here'sthe very lengthy report while verifying:
