For instance, the people at the podcast ScienceVs cover many things very well. I don’t think the host even has an advanced degree. There is at least one PhD on staff.
She is not a journalist, she is a physicist. Even in physics her takes are not that impressive. What she has been pushing for years is something like “the mainstream theoretical physics is wrong because I want it to be, so we should stop encouraging it by not making their experiments and start doing small less costly experiments”. The problem being there are rarely any ideas for any such things.
