Whether you are growing mushrooms from spores, culture or spawn you will find that the process is much the same with each having its own separate advantage.
Growing mushrooms from spores is good if you are ordering psilocybe cubensis online because it legal in most places to order spores.
Spores are also good if you want to experiment and create your own strain of mushroom because every time you grow a new mushroom from spores you are creating a new strain of that species.
The preferred way is to put spores into an agar plate or agar liquid that way you can easily see if there is any competing fungi that is growing. Then once you have a good growth you can transfer it to other plates as well as to your different substrate to grow out and fruit.
Cultures are good because you are not creating a new strain and are more predictable. You can then follow the same steps as with spores.
You can always take you spores or cultures and put them directly into your substrate and by pass the agar plates and liquid but are at higher risk of losing all your substrate.
Finally you can order pre-made mushroom spawn where someone has done all of this for you already.
