Thanks for the followup. I'm on Monterey, and there are a hundred or more Noto fonts, and a hundred or more other unwanted fonts as well. This may be addressed in newer OS, but I hesitate to upgrade b/c I also have music software, Logic Pro and various plugins, and they frequently have conflicts with MacOS version upgrades; researching the real compatibility is a significant nuisance, so...
Anyway, I found a useful solution for fonts with Affinity:
Affinity Designer has an extra menu next to fonts, in the inspector, which has a few font groupings, and by selecting "English" the extra Noto and non-Noto fonts magically go away. This is great, for me, as I'm only working with English language at present.
For anyone working with some-but-not-all foreign languages, I found that Apple's Font Book utility lets you create groups of fonts (and it doesn't burden you with the multitude of extra Noto-etc fonts) -- and these groups from Fontbook will appear in Affinity Designer's font grouping dropdown menu!
Very useful.
