Upskilling as a PM

I'm currently an APM (1 yoe). Even though the pay, wlb is much above industry standards I feel an itch to work and build in an IC role before eventually turning to PMing.

So here are my options:

1. Data Engineering
2. Data Science
3. Software development

SDE to PM would be pretty standard with a wide range of options available but wanted to get opinions on what niche PM roles do DE and DS open?
