In all honesty, the only opinion that matters is your wife's...+1000. Take it from a guy who's been married three times. Your used cast-offs are not an acceptable gift. Get her a new camera and lens kit that is her's and her's alone. Even a 1Dx would be a bargain in comparison to the path you'll be heading down if you dust off some 10 year old camera and hand it to her.
In an ideal Canon world, it would be so easy to answer this with "EOS-M2"...
- very compact, "cute" and cool body ... depending on wife's colour preference in black, white or red
- sensor with very decent IQ ... in good light
- good-IQ lenses available, compact and reasonably priced, especialy in kit
- compact 18-55 kit-zoom with IS and even more compact, "cute" 22/2.0 WA prime
- highly intuitive user-interface including touch screen
- built-in WIFI, sharing of images possible, depending on how Canon has implemented it
- M2 not for sale in US, Europe and most of Asia
- M (and M2 probably as well) AF performance not sufficient for intended primary shooting situation - social pics, mainly indoors (=usually low to very low light, people typically moving)
- No built-in flash; separate flash unit no enticing option here
Therefore I'd go with SL-1 with 18-55 STM or possibly 18-135 STM if it's got to be a Canon and a DSLR.
EF-S 17-55/2.8 is a great lens (use it as my primary lens myself), but too heavy and big (basically same size as 24-105L) to be a good choice in this scenario.
Nikon1 J3 might be an even better choice. Small, very "cute", very good AF-performance, built-in flash, IQ "more than good enough" for intended purpose. Dirt cheap. WiFi available via WU-1b plug-in wart.
Or Sony 100RX II. Very compact & light, decent lens, decent IQ for intended purpose, flash and WiFi on-board. Might take convincing of wife and Jones' that it is not just another el-cheapo P&S cam, though. :-)
