I think you are misunderstanding. These are typically mathematical tricks used for computation and don't lead to actual non-local interpretations of QM. I don't think any major work is done without standard QFT.
I doubt you can find any serious Theoretical Physicist who believes retrocausality or FTL information transmission is compatible with the Universe we observe.
Anyway we've diverged off the actual crux which is that Quantum Conscious Woowoo theories require types of hidden variable theories which are not coherent with this Universe.

Bohmian mechanics is an explicitly non-local theory of QM, not merely a computational trick. It actually makes predictions that differ from QM in non-equilibrium regimes, but is consistent with QM in all regimes currently accessible to us.

I don't know what "major work" means. Work in quantum foundations is done without QFT all of the time. Yes, QFT is a useful effective theory, but that's a far cry from the original claim about the nature of reality, ie. that there are necessarily no hidden variables. Literally no experiment has ruled out hidden variables wholesale, only certain types of hidden variables.

Maybe consciousness would require hidden variables, but your conclusion is still based on a fundamental error, which is that we have observations that are inconsistent with hidden variables. Since this claim is in error, then the conclusion does not follow.
