Well real life has intervened for the moment, so I haven't had time for any more experiments... mostly.
I did order one of these 9" "Super VGA" CRT monitors to test:
http://www.ebay.co.uk/itm/121770406890
It is advertised as 800x600 resolution, but so far as I can tell it is plain vanilla VGA. It syncs fine at VGA, but loses horizontal sync on Macintosh 640x480 which is about the same horizontal rate as 800x600 @ 60Hz. It's also advertised as having "faint screen burn", if you count having the words TILL 02 CLOSED DOWN in heavy letters "faint".
But mainly I bought it because I thought the comparison of the internals to the compact Mac could be instructive. Here are a few initial photos. Sometime later I may take some measurements on the yoke or flyback transformer, and possibly see if the video amp circuit is worth emulating.
