Why meter and place your background in Zone V if you want it in Zone I or even Zone 0? Place the shadow/low values where you want them to be in the print.

The development compensation related to the reciprocity failure adjustment takes the expansion of the highlights into considerations and compensates for them. You don't need to do anything else (assuming, of course, that you have a tested and working system for your film/meter/development for reciprocity failure compensation...)
However, if you find an N- or N+ development is necessary before you start compensating for bellows and reciprocity, this "-" or "+" should be figured in to your final development compensation. Example, you want to expand contrast and choose N+1 development. After all the adjustments, you find that you need N-2 development for the reciprocity failure time you have chosen. Simply add N+1 and N-2 to get your final development time: N-1.
If you place your "black" background on Zone V and do everything, you'll end up with a negative overexposed by 4 stops. (Plus, by placing shadows correctly, you'll likely have less reciprocity failure to deal with!)
So, meter and place the background. Meter the flower and see where it falls. Determine a starting development scheme. Figure in all your adjustments. Adjust your final development scheme by your starting one.
