Short question:
Every cube should have a single load of 2500 N.
Is my input correct? Or must I use an area load
of 10000 N to spread it over all 4 faces?

Use 10000 N
Last post was quite short because I was on the way.
In force constraint the given load is distrbuted on the sum af all given face area. Means to get 2500 N on each of faces with the same area you should apply 10000 N.
