Asking here bc others may be in a similar position.

Software developer in the data/platform/python space. I have training funds to spend in the next 12 days. There are plenty of paid resources out there, but relatively few seem better than reading the docs end to end.

What paid resources have folks found better than the many free resources available? This could be courses, books, newsletters, etc.

Note: I already own Designing Data Intensive Applications.
