No need for 12guage speaker wire...14guage is more than enough (buy 2 x 50ft). But do estimate the total length required.
I wouldn't get the monoprice banana plug. I had similar one and the wire tends to come out of the plug, if we accidently pulled the wire as the speaker wire is not screwed to the plug. Currently, i am using nakamichi and have no issues.
Other 2 looks okay for start. What is your purpose for rca wire?
I have measured and I would need 85 feet including bi wiring for the front speakers. I'll have a look at the nakamichi plugs.
Rca is for the subwoofer.
The AVR will be hooked to samsung led 55 inch (the frame tv 2019) which is hdr capable.
