Cell quality is important. You want to be using known good quality cells like those from Panasonic, Samsung, LG, etc..

How you manage temperature, charge and discharge is also really important, dendrite growth can cause cell failure in time. Charge temperature is extremely important. So you want to make sure you're using a smart programmable BMS where you can set up all the protections properly. Ideally one with as many temperature probes as you can find, 4 is good, 8 is better and some will have that many.

Otherwise making sure nothing can short out internally is important too, but it sounds like you're putting some thought into that. Most critical IMO from what I've seen on pre-made battery packs is making sure your series banks are well insulated from each other and have no chance of vibration causing the cells to wear through their heatshrink and touch each other.
