Can you give any alternatives, other than the multiple cheaper options/suggestions already given?
Rear wheel seems dramatic and completely unnecessary. 9 sp uses the same wheel as 10sp and Tiagra 4725 is a short reach hydraulic sti lever. It does require its own rear der and it would start making things expensive, not quite to the level stated since Europe gets much better pricing then the US but still up there but more like 500.00 which isn't horrible for what I consider a really decent group.

This is the real route I would go; I've done the Juin Tech on my wife's cross bike and will get some for her gravel bike. The TRP are slightly better due to the pads self setting as they wear down where the Juin Tech require cable adjustments to compensate for pad wear. The Juin are noticeably lighter and have a lighter action which is why I went with them for my wife.
