Nice, pretty impressive I bet. That RF and Alpine are good products and should sound great. AND, those Morel hybrids are really fantastic!
CCA can be used and it sounds like what you did will be fine. Even 14 gauge CCA is going to be more than adequate for speaker cables. For mine, I use 16 AWG OFC for speakers and it is often more than needed anyway. I only use large gauge wire on my subs where there is a substantial power input. As for the EQ, there is a ton to learn and youtube is your friend. Tons of YT vids on extensive Helix tuning options. That is something you will want to study a bit, jot down the process for the type of tune you want to pursue, then trial and error. My recommendation if they didn't do time alignment is start there. Some in here like to start with getting the overall response flat, the x-overs done, then TA and short of the TA, that has already been done so you get to kind of pick up where they left you.
Did you get a calibration mic? if not, Dayton has some really inexpensive ones that plug right into the 3.5mm or USB-C port on your laptop (I don't think that there is a REW app for your phone, could be, just not familiar if they doi) and allow you to take measurements of your system at the listening position. I have this one:
Dayton Audio UMM-6 USB Measurement Microphone
There are others too:
Dayton Audio IMM-6S Calibrated Measurement Microphone For Tablets IPhone IPad And Android
Dayton Audio IMM-6 Calibrated Measurement Microphone For Tablets IPhone IPad And Android
Dayton Audio IMM-6C Calibrated USB-C Measurement Microphone For Apple/ Android
This assumes you want to dive all in.
Once you can actually see what that sound looks like, you can go from there. It will tell you the highs and lows, nulls, all that stuff. It's a bit of a learning curve. If you just want to do it by ear, then at least watch some YT vids on Helix and time alignment and get that part going for sure. That is the difference in it sound great and sounding like a setting in a giant set of headphones.
