As a creator myself, my personal recommendation: outside of very specific use cases, ProRes Raw isn't worth it. A good lens and good lighting shot in s-log with a good color grade is more than enough, and it won't cost you thousands in storage
In my experience, you can save a ton of money by a) making it good in production rather than post and b) making sure your workflow makes sense for you. Do you need to be transferring media between machines? Maybe you do, but does it need to be all media? Would a NAS be a better use of money?
Don't get caught up in fancy shiny gear unless it's actually serving you and genuinely helping you make what you want to make. And buy used! Less e-waste!
