Optimal Spanning Tree Configuration for Dell N2048, Dell 6248, and Dell N1524 Switches

I have this fruit salad in our switch infrastructure. From what I've researched, RSTP is the common spanning tree mode among all these models below.

What would be the best configuration for Dell N2048, Dell 6248, and Dell N1524?
