You need to install GAMLj3 module. There you find generalized mixed models

Re: GLM Mediation with 3 level categorical factor
As for any other genaral linear model, also in mediation the effect of a categorical variable is represented by K-1 contrast variables, where K is the number of levels. If you want to change the reference level, go to the data tab, variable properties, and set your reference level as the first level...

Re: Error message 'the condition has length >1' for SEM Model
Hi there was an issue with the module. Update to next version (1.2.2) and it will work (it coming up tomorrow). In the meantime, you can run your analyses selecting "Missing pairwise" in "Model Options". In your data this option does not change anything (you do not have missing) ...

Re: mean centering & variables scaling
1. sure, that is the default. With mixed model is always a good idea to center the covariates (although not necessary)
2. any factor is transformed in contrast variables and their coding is mean-centered (if do not select "dummy" as a coding system)
3. yes

Re: Lmer and glmer in jamovi
Here is jamovi to R:
General Linear Model-> lm()
Generalized Liner Models -> glm() (plus some specific commands)
Mixed Models -> lmer() and lme()
Generalized Mixed Models -> glmer()
Gamlj uses a lot of other R packages to accomplish specific tasks, but these are the basic R commands.
