Used a tripod this time – wow, that was so much easier
I compared all f-stops from f/2 through f/22, plus tried combining the f/5.6 bokeh around the edges with f/11 in the center in Photoshop, but I didn't like the look as much as the single f/5.6 shot – too much character lost stopping down. f/5.6 was the best f-stop for color, contrast, bokeh, overall rendering. Focus stacking will be the next experiment
