OK, thank you Ulrike.

For the document in question, everything that does not require a more exotic font than Noto Serif is set in Bold Italic, so loading the non-bold, non-italic by default would accomplish nothing useful in the present case.

This (presumably) allows me to say that I want a 1 cm version of Noto Serif at 1 cm (presumably on a 1,2 cm leading) henceforth, but how, in a call to \fontface, can I /load/ the font at (e.g.,) 12.2pc so that I can use it at that size thereafter without requiring a \fontsize command ?  Since I can write "Scale=", it is not clear to me why I cannot (apparently) write "Size=".
