I'd just take all the info from chums here, then just think about what you are able to buy.
We're short of compost this year owing to lockdown, so we just take what there is and make it work, there's no rocket science involved, so lucky you, you don't have to dig anywhere, and can use whatever is available!
Let's face it, no company is going to go to the trouble of producing a bad product, because gardeners just wouldn't buy the stuff!
Good luck, and best wishes to you for a decent harvest!
