CCA wasn’t probably your issue there, CCA is actually becoming the standard everywhere because copper is way too expensive and to be fair not needed with modern hardware.
You most likely issue with that CCA is the AWG size you picked, cheap cable is usually 24, 26 or even 28 AWG and those will be bad.
If you want PoE or anything gigabit or above you need to pick 23 AWG. This is considerably cheaper than full copper and it will work fine for the max. rated 100m. Either way, cheap 26 AWG should be able to deliver gigabit and PoE at short distances like 20 meters or so.
Another important thing is to make sure your terminations are properly done and the plugs are good. Meaning, no Cat5e connectors should be used, always use staggered ones:
