You want stiffness, not necessarily sheer strength. I am not sure how much it actually matters especially at high infills but every bit counts. PLA is great for us, the only downside is the said low temp resistance and isn’t forgiving when it comes to over tightening.
What kind of printer is this? If it can do abs, why not PETG or PLA? Both can be printed and are somewhat preferable to be printed on heated beds and enclosures. Another thing to be noted as that if you print too many parts at once, your layer adhesion might suffer. The layers may cool off too soon if there is a ton of geometry to cover in just 1 layer. Fast machines don’t have this issue
