So last year I was in the feed zone chatting about this same stuff with a mom. Her kid was a Cat 4 14 year old at the time.
They decided to use the same trainer and same methods. He's now a 15 year old Cat 2. Same stuff.
morning HR, i find, is a relatively poor indicator of one's rested state, esp as it can change based on the season (e.g. off-season vs in-season).
spo2 attempts to add another layer/indicator. i've used it in high-altitude (above 20,000') climbing situations, where it can carry a great deal of meaning...life-or-death.
personally, i find HRV overnight to be the best indicator i've come across to integrate both training stress and life's other stressors to become
predictive of performance.
IME, CTL, and TSB are good at quantifying what has been done but not so great at predicting performance.
ymmv.
