If you listen to Laguna Hills Nursery (videos on YouTube), you shouldn’t use any wood products (compost) in potting soil.
I’ve just started to trial this recommendation, which is basically contrary to the entire Ag industry (potting soil companies).
I’m using 50% peat moss and 50% pumice (alternate equivalent coarse perlite is easier to get than crushed pumice) for potting soil. There is another potting soil mixture of 1/3 peat moss, 1/3 crushed pumice (or coarse perlite), and 1/3 sand, charcoal, and clay that results in less compaction over time.
btw... they recommend sand as the best growing media, but that weighs a ton.
