Do avionics in general subscribe to MISRA C/C++ or do they go even further with an additional (or different) approach?

Depends on the company in my experience. I've seen some suppliers that basically just wire up the diagram in Matlab/simulink and hit Autocode. No humans actually touch the C that comes out.

Honestly I think that's probably the correct way to write high reliability code.

You’re joking right? That autogenerated code is generally garbage and spaghetti code. It was probably the reason for Toyotas unintended acceleration glitch.

Do you have any evidence for "probably"?

I know for the fact simulink generates spaghetti and spaghetti code was partially blamed for Toyotas problems. Hence the inference

That's a nonsensical connection. "Spaghetti code" is a very general term, that's nowhere near specific enough for the two to be related.

"I know for a fact that Italian cooks generate spaghetti, and the deceased's last meal contained spaghetti, therefore an Italian chef must have poisoned him"

SRS is a for-profit corporation whose income comes from lawsuits, so their reports/investigations are tainted by their financial incentive to overstate the significance of their findings.
