Purely anecdotal of course, but as a person that struggles to do sports consistently: for me, the thing you are saying this does not prove is absolutely correct. As far as my body is concerned, not doing any sports for months will get me way better sleep then when I do any amount of exercise after 6pm. As a matter of fact, if I do exercise (cardio) that late, I can guarantee that I will not be able to fall asleep before 1-3 am. Even if I do it consistently for a few weeks. Obviously just an observation of my own body. But it's the reason why I will no longer even attempt to do anything remotely like cardio post 4pm

I've found that this is true for not cardio workouts like climbing as well. It's truly unfortunate since that's typically when I have time, but staying awake until 2 isn't worth it.

Anecdotal support incoming: I work out twice a day, 15-20 minutes of lifting in the morning and 15-20 minutes of exercise bike in the afternoon. Have done for about the last 2 years. I also can't exercise after about 8 (I typically lay down for bed at midnight or so) or I'm up all night. I'm thinking that there might just be some sort of something in bodies where physical exertion induces a physical exertion mode to operate in that precludes sleep for a while. It kinda tracks in an evolutionary biology sort of way (despite that field being speculative an untestable): we didn't used to exercise. We used to exert ourselves when we needed to to stay alive and just sort of hang out and rest when we could get away with it. Having two modes, one that says "We're safe and comfortable and can lose consciousness for a few hours now" and another that says "Idk what we're doing but we're doing something and need to not fall asleep for a bit" has pretty obvious advantages compared to a system that allows you to take a nap in the middle of climbing a tree to avoid a predator.

More anecdotal data. I’m not a morning person by any stretch, but after decades of training on the evenings I switched to morning workouts where I wake up at 4am to get to the gym I’ve founf that I have less sleep interruptions, now I don’t if it it was due to all the water intake before or that now when I finally hit the bed I’m already exhausted.
