I worked on Scuba, inside and outside of Meta (Interana), and yeah - It was expensive AF. I recommend focusing on metrics first. Use analytics logging sparingly, and understand the statistics of how metrics work, because without understanding those statistics you'll misread your events anyway.
This is not to say that wide events aren't worth it - For many things, something like Scuba or Bigquery are invaluable. There's ways to optimize. But we're talking about "One of AWS's largest machines" vs "A couple cores", and I suggest learning Prometheus first.
