Where are you geographically?
App Academy and Hack Reactor were the top 2 bootcamps as of a couple years ago. I don't really know how they shake out nowadays, but App Academy still does have a "placement based plan" where you do not pay until you get a job (in my day, that was the only option). This would seem to indicate to me that they're still doing well with placing graduates, and for somebody as driven as your wife seems to be that's probably a great option. If you live in NYC/SF or can relocate (I'd recommend SF), have her start the application process.
I went there and at least one other forum member did too, we got jobs we're happy with but that's ~4 years ago now.
I don't know how it is for startups, for programmers at large non-tech companies (like banks), or for people in small cities. But at large tech companies in the Bay Area it's amazing (there are possible exceptions, and some like mine prioritize work-life balance more). Shouldn't expect to be somewhere working > 40 hours for any great length of time if you don't want to be.
There are older threads about this.
I haven't actually done
https://www.freecodecamp.org/ or talked to anybody who's done it, but it
looks good and it may even be a suitable free substitute for a bootcamp. I do think your wife can just learn on her own if she wants, without needing the bootcamp. Would start with Python and React if she doesn't go with freecodecamp or start applying for App Academy.
