I suggest using the simpler first method for all cases.

The second example was just an experiment to see how entangled the
decisions about placement can become.

If the accent and fermata are placed depending on where the cross-staff slur
goes, they don't get a permanent space reservation until the slur is placed,
which is after staves are spread on the page.  When I set Scripts as
non-cross-staff in your example, it looks like the dynamics avoid a tentative
placement of the fermata and accent, both scripts being placed on top of
each other just clear of the note-head .
