And I forgot to mention: Unfortunately, your offIIb.ly file doesn’t place the dynamics in the middle of the staff symbol as they should be – probably because of outside-staff-priority?

No, the Y-offset callback will return the same values whether outside-staff-priority is its usual value or ##f.  \offset takes the result of this Y-offset callback and offsets against it.

This is probably not what you want, but there's a tricky way to offset against a user value, involving a combination of override and tweak:

 \relative {

  \hideNotes

  \dynamicUp

  \override DynamicLineSpanner.outside-staff-priority = ##f

  \override DynamicLineSpanner.Y-offset = 0 % try other values

  b'2

  -\offset DynamicLineSpanner.Y-offset 2

  \< 2\f\>

  2 2\f\<

  2\f

}

Here, of course, we could simply do the following :)

\relative {

  \hideNotes

  \dynamicUp

  \override DynamicLineSpanner.outside-staff-priority = ##f

  \override DynamicLineSpanner.Y-offset = 2

  b'2\< 2\f\>

  2 2\f\<

  2\f

}
