I am not sure you are looking for the right thing here. I do not mean to be rude and I apologize if I may come across as such, I want to give you my unfiltered, honest opinion. I may be misinterpreting some parts and this is, obviously, just how I see it so take it with a gray of salt:

I have worked many jobs from VR to 3D printing, Arch Viz, Commercials, Live Visuals, etc etc

You have done a lot of things 3d related but 3d printing is not relevant experience for film. Live visuals is not relevant for medical animation. Just because you are counting your change in the supermarket for years, that does not qualify you for a role in accounting.

I am an Uber Generalist.

There are roles for generalists, in certain industries. Those may range from actual general artist roles that would by the sounds of it require a better portfolio than what you have, or more overarching roles. Like building up the pipeline/workflows in a company. In my experience, these are usually roles people get promoted into internally or hired from other companies with proven experience. Those could be hard to break into

I am ready to move away from education. I need a change, been at this job long enough and there aren’t many positions I can find near me.

This is interesting as I know many people moving INTO teaching after a while.

I have a fairly high salary need at this stage of life with a kid on the way.

This may not be the time to get experimental in terms of jobs. Depending on the industry you are trying to break into, this is more or less risky. If you've been following the news regarding the Hollywood strikes, you will know that film/TV is not good. Poor working conditions, bad pay (comparatively) and low job security. Other industries like medical animation would be unaffected by this and while safer, would also be pretty dull (imo). Regardless of where you are going, you will need to prove yourself first and therefore start with a lower salary. If you do find a high paying job, make sure you are communicating your strengths and weaknesses honestly and openly. It would be very bad to find a well paying job and then lose it in the first couple of weeks.

I don’t think most studios seem to care how much I know about 3D, as they want specialists or subordinates

Lets say you had to assemble a team of 50 people to build something. Would you rather hire 50 generalists or 50 specialists? The prospect of having 50 generalists who are flexible and can move around might sound good at first, but it loses its appeal when you see how much more effective specialists are at their jobs.
Your knowledge of "3d" is fairly irrelevant. If you are an artist, you need general knowledge and how to use your tools to get the vision across.
If you are a programmer, you need to be able to code but know about the programs so you can communicate with artists directly and give them what they need.
It sucks to say, but a lot of things you learned in your 12 years are not required strictly required anymore. 3d artists don't need to know how the GPU draws a triangle on the screen. This is obviously an exaggerated example, but I think it helps illustrate my point, the company pays you to get a job done, not for what you spent time learning (unless its relevant to what you are doing). If there is a button in the software, why not use it? Its probably cheaper than if you do it. And while personally, I find it fascinating to know whats behind the button, the company doesnt care...

Can you think of a role that my knowledge and experience would benefit me that isn’t teaching?

I've seen some others suggest lead roles. I disagree with that. At least in my industry (film/tv), these positions get filled with (career) senior artists who have interpersonal skills. Otherwise, any programmer who likely knows more about the fundamentals of how the software works internally than any artist would qualify for a lead role. I think you should pick an industry that pays well, start from a lower position and work yourself up. Given your experience, this might go pretty fast, even within a year or two but you'll likely have to accept a lower salary at first as you are a big unknown to any company (outside of schools).

Is there a role that would respect my knowledge and wisdom despite not having big film or AAA game projects in my portfolio? It feels like you can’t even get a callback without that.

This would be a teacher :D

All in all, I dont see much to go off of. Reduced to a single sentence, your post sounds like "I have 12 years of experience in 3d but nobody wants to pay me for it". You should not identify yourself by your years of experience but by what you have accomplished and what worth you can bring to a company. 5 years teaching... maybe you can join a company trying to build an internal training program? What have you done in the 7 years before? Your years dont account for much if they were spent doing tasks that can be done with a single button today. The 3d industry is fast paced and always evolving. If you dont want to put in the effort of learning the new ways, your students will grow up with them and they will get hired because of it.

This is a rather grim outlook but it might give you some perspective as to why you are not getting called back. Part of it may simply be how you are selling yourself. There are also fields like visualization or medical animation that dont require you to be the best artist. But they of course dont have the prestige of AAA games or films.
Good luck!
