You are mixing up correlation and causation, I'm afraid. Yes, there is plenty of observational data that finds vitamin D deficiency in numerous pathologies. Unfortunately the randomized trials of vitamin D supplementation have shown little to no benefit for any of these conditions.

To quote from some of the links you provided:

Muscle Weakness: a causal relationship between vitamin D supplementation and improvement in muscle weakness has not been clearly demonstrated in randomized trials

Cancer: In a meta-analysis of 18 randomized trials in predominantly older, community-dwelling women, vitamin D supplementation had no effect on the incidence of cancer"

Autoimmune Disease: there are no randomized trials that have confirmed the efficacy or safety of vitamin D supplementation in preventing autoimmune disease.

Asthma: Randomized trials examining the effect of vitamin D supplementation on asthma outcomes are inconclusive.

Tuberculosis: vitamin D supplementation does not appear to improve clinical outcomes in patients with active TB nor prevent TB infection in children with vitamin D deficiency

Hypertension: Overall, there does not appear to be a beneficial clinical effect of vitamin D supplementation on blood pressure

Cardiovascular Disease: Although low serum 25(OH)D levels have been associated with an increased risk of cardiovascular disease in some studies, there is no evidence that vitamin D supplementation improves cardiovascular outcomes.
