For the later jazz chorus:

walking bass may already be active.

So keep RH compact.

• nearest-guide-tone shells
• one altered top-line motion at important cadences
• tritone substitution with minimal RH movement
• blocks only at selected climaxes

The sophisticated sound should come from voice-leading, not from giant hand jumps between exotic chord shapes.
