You don’t need a fancy oven, I know a guy who makes great pizza in a crappy rental-apartment oven.
I think a pizza stone helps.
00 just indicates the finest grade on the scale 00 - 0 - 1 -2. Different flour brands use different mixes of wheats. Caputo makes at least three for pizza, “pizzeria” aka blue, “rinforzato” aka red, and “chef’s flour” for long fermentation, plus “pasta & gnocchi.”
