#1: CISC has gone largely (entirely?) extinct
Citation needed? Isn’t x86 considered a CISC?
Yes and no. AFAIK when coding assembler for these chips you use CISC-instructions but they get translated into RISC-instructions by a hardcoded mikroprocessing-unit (not sure about the real term). So the processor itself gets RISC-instructions.
In reality it seems to be more complicated: https://fanael.github.io/is-x86-risc-internally.html
