Job openings were a leading indicator in the last recession, see "Planned Next Three Months and Current Job Openings" in https://www.nfib.com/assets/SBET-December-2019.pdf (I ignore planned as it seems noisier). There has been no substantial decline since 2010. The decline in recent months is bigger than in 2017 but could still be noise.

The yield curve is relatively standard economic news: https://www.forbes.com/sites/greatspeculations/2020/12/31/th...

Unemployment is used to define the recession so once that starts increasing again the process is already well underway.

I agree though, predicting a recession is like reading tea leaves. The data is so fuzzy and updated so infrequently that it's useless for practical decisions.
