Is there a way to calculate SE for the factor scores from the EFA output? We are able to calculate the factor scores themselves, and we are trying to avoid re-running a number of EFA models in CFA format.
We add factor score standard errors for more cases as we develop new program versions.
But if you want to focus on using factor scores, Bayes and its plausible values is a good way to go.

Thank you - I actually am not fully aware what I should do to best take advantage of the factor score standard errors. I guess I could construct confidence intervals and see how the factor scores differ from each other at different levels?
Re focusing on factor scores, it's mainly for specific modelling situations, for example, in ESEM, sometimes the factor structure can change depending on covariate - even the covariate is not part of the model.
Another reason to use factor scores is for colleagues who do not want to go into latent variable but still want to take advantage of psycho-metrically defined variables. But apart from problems of computing factor scores itself, I found in settings such as the bi-factor CFA, the 0 correlations between factors are ignored in factor scores. Although I have not tried Bayes yet, but the idea of plausible values sound much better in general.
