I think you would use it enough to have a WFO, for bread if nothing else. If you decide that you don't like Neapolitan, you can make any style you want, including deep dish and Sicilian. I usually make one or 2 Neapolitan style first then bring the temp down for 3-4 minute pies for the remaining 4 or 6 I usually make.
Ceiling height is somewhat related to size, but 15-18" for a 40-42" would do well for bread and pizza of all types.
