I use #4 perlite and lump charcoal broken to size along with lava rock and LECA (if some is around) that is the base mix. For plants that want a little more water I’ll add 1:10 big bark pieces
I keep a tote (15 ga) of the base mix in hand pretty much all the time and it makes potting and repotting a lot easier.
For what it is worth. Nothing is easier that SH for potting and repotting.
