I think you answered your own question.
The 1st thing to do when shopping for a compressor is to figure out what tools you want to plug into it. Sanders, bead blasters, and some paint guns require A LOT of air. Find the tool that has the highest SCFM at XX psi consumption that you will be using and then find a compressor that will meet those air needs - many recommend 25 - 50% over capacity to prevent the compressor from running continuously and burning up the motor. Without knowing the requirements of your air tools, it’s impossible to tell you what compressor to buy.
