Would it be OK to use sand from the beach to add to the potting mix (plus perlite) used for succulents?

Ocean sand contains salt that will be deadly to your succulents. River or builders sand is better. But perlite is the best way to add porosity to succulent potting mixes.

sand doesn't actually aerate well either. Think of the damp sand you pack to make a sand castle. Water does run through sand, but it stays stuck between the grains so no air for roots.

No. Beach sand is too fine and will fill all the spaces in the soil, turning it into a big hard block. Construction (river) sand is grittier and works for this purpose, especially after you pass it through a window screen to remove the fines.
