Hi rickcsc.
Re: "Vision Pro apps : Does the Vision Pro have the Shortcuts.app as seen in iOS?"
Apple does list the Shortcuts app as being available on Vision Pro.
See: Apple support's online article: Apple Vision Pro - Technical Specifications - Apple for a list of apps and more.

Re: "Vision Pro looks to be perfect. Or is there a better solution?"
Am no expert in this area. Wondering if your wife may have a medical / professional specialist who may be better able to advise / inform.
Seems you navigate Vision Pro by using your eyes, hands, and voice.
You may like to watch a 10 min video of someone being introduced to using Vision Pro and some of the features:

Also: Apple do have Accessibility Support options:
Eg: How to contact Apple for accessibility support - Apple Support
or
Apple's Accessibility Support Website (info. / support / contact options stc.)
(NB: You can "Get Support" from the link at the bottom of their website:)

All the best :-)
