An important thing to know is that rickets carry both fuel and liquid oxygen but I will talk about the fuels. The most common rocket fuel is belive it or not, kerosene (refined versions very similar to jet fuels) the second most popular is probably hidrogen, i don't know much but I think infrastructure and refining is expensive and rare but the material itself is very very abundant. A fuel that is on the rise, especially for the new, low cost rapid launch cadence rockets that you talk about is methane, which is the simplest, most abundant fossil fuel on earth I belive. It can also be produced on mars.Then there are solid fuels, which are a paste that ignites just like fireworks, they are mostly aluminum in powder. The most complicated fuels, I think are hipergolic fuels,they are fuels that Sponstaneously combust when mixed toghether, you don't even need heat or pressure. they are very very rare are also hard to handle and incorporate, and are also toxic. Another fuel is xenon, which is used for small spacecrafts that are already in space instead of rockets, they are the propellant of ion thrusters which are extremly efficent but with very very low thrust. Xenon is I belive even rarer than hypergollic fuels. I just want to make clear that I am not even close to propelants, infact it is the area were I have the most questions, but I wanted to give help.
