The latter two are very much variable by company, but those are the general trends. They'll also vary in importance to different people. The former item, however, can be just as burn-out/tedium prone as tech company stack whiplash.
It does help - as you point out - to be in the position where the non-tech company will almost always take your advice if you tell them they need to change platforms. But the most effective way of getting yourself in that position is to prove that you exercise that option only when it truly is in their best interests.
And so will be the workload. No semi-mandatory after-work drinking, no constant "hustling", no bullshit.
But then again, I like my own yard and sitting by my fire pit with a beer, and I don't spend too much time worrying what other people have.
But it's easier to get a company to upgrade from old cruft to a commonly-used technology, of your choice and which you push, over trying to get the company to drop a new fad they've bought into ("You know, we don't really need all of those Docker images, and VMs, and Amazon Cloud services - let's just write an executable which does the thing and can be configured.")
Some possible factors are that the company is not that big and we have a feature list to deliver. We are not VC, so we cannot afford to burn money. The devs churn is low, so we don't need to be attractive to many people all at once.
TBH, I don't like it all the time, but it works and our clients are happy with the results.
Out of the blue, one of your main suppliers declares they will accept orders only through a REST interface starting next quarter. And that you can/must use it to track your orders, instead of sending an email to one of their employees.
One week later, you are required to provide invoices in PDF instead of just printing on paper.
And your accounting system will switch to Oracle Finance in October...
Your ERP was developed on Progress ABL, and nobody really cared to port the old code to a web-based architecture because it was just for "internal use" and Putty was fine.
And maybe these were introduced in other companies because their IT depts. are run by "fashion of the month", but whatever the reason, you now have a problem. And if your sw and your skillset has remained frozen in jade since the early 90s... this will be painful and probably require at least one false start before getting it to work reliably.
I have noted a tendency in people who work always on "very stable" technologies to go in crisis mode as soon they have to (for example) produce a file in XML or JSON format after 2 decades of CSVs... this unfortunately almost routinely ends in stuff which is very brittle ("XSD? you do not understand, we need to produce an XML, ... I dunno what an XSD is or has to do with this requirement - except that they both start with an X, maybe - so please do not make things unnecessarily complicated and just go back to coding, we were supposed to start testing one week ago.")
Implementing orders in REST was probably done in a couple of weeks of work. PDFs have been there since ever.
That is not always true, it also depends on who they are selling code do..
I know a few Orgs that by code from others, and pay $$$$ to ensure it never changes... or rather only changes in measured approved ways not drastic changes that would up in business workflows.
So I would amend your statement to where people write code for companies that sell code to startups or technology companies
if you are selling code to a 100 year old manufacturing company, or some other legacy space (healthcare, education, etc) then most likely they want stability not the new shiny
