See this wp cmb primary anisotropy section for interpretations of the power spectrum peaks, and adiabatic density perturbations vs isocurvature density perturbations. The CMB can distinguish between the two: “adiabatic density perturbations produce peaks whose locations are in the ratio 1:2:3:...[56] Observations are consistent with the primordial density perturbations being entirely adiabatic, providing key support for inflation, and ruling out many models of structure formation involving, for example, cosmic strings.”

The Hubble tension might be pointing towards new physics, a possibility which has been the subject of significant study in the literature: see e.g. [88–137] for a selection of works examining this possibility. However, as pointed out in a number of recent works (e.g. [138–140]), it is important to check that proposed solutions are consistent with BAO distance measurements Soundness of Dark Energy Properties, pg 8.

Cosmological parameter inference with Bayesian statistics [1903.11127] The main aim of this work is to provide an introduction of Bayesian parameter inference and its applications to cosmology. We assume the reader is familiarized with the basic concepts of statistics, but not necessarily with Bayesian statistics. Then, we provide a general introduction to this subject, enough to work out some examples
