Small, minor suggestion: maybe there are free, open source tools that are equivalent to what your wife might be expected to know...you being a techi can spin up some of these free tools, and she can gain some - though minimal - experience...and in her resume, or maybe cover letter tie her experience to these free tools as "similar to the industry standard set of tools...", etc. This helps because it inserts the keywords of industry standard tools, enabling the automated scripts to help get her on HR-system search results...but its not lying since the resume/CV states her experience is adjacent or something...and by then maybe a sympathetic hiring person might give her a shot? Obviously, this is a tiny tactic part of a greater set of strategies that she couild employ. ;-)
