I tried weight lifting/strength training for about a year and never really noticed an improvement in sleep quality. However, it was still a net positive in the strength/overall daily energy department.

I used to bike a lot, stopped after a leg/back injury (not from biking), but I picked up an eBike about 3 years ago and absolutely love it. The pedal assist takes enough stress off my leg that I can keep it on the lowest setting and ride for hours, which feels really, really good and does actually help with sleep that night. This, of course, is weather/season dependent but I relish the times when I can just hop on after work and go somewhere.
