Pro-mix will work well. There’s better self-made-mixes I’m sure. I use Pro-mix for everything in containers.
For cuttings I suggest the paper towel method. You take dormant/hardwood cuttings and wrap a slightly damp paper towel around the bottom 1/3 or 1/2 of a 6-8" cutting and put a batch of them into a ziplock bag and then put them in a dark area with the bag open/not zipped shut. I use a kitchen drawer because that’s how I saw @tonyOmahaz5 doing it. It works awesome. Some people go thru a lot more ‘trouble’ than that but I see no reason to do so.
Grafting is an acquired skill on any woody-plant. If you don’t have experience I would suggest you begin practicing cleft grafting on dormant wood off anything whatsoever. Or, buy a Zenport V grafting tool for 25-35 bucks. Here begins talking about fig grafting using this tool:
