In the real world there is no CISC or RISC anymore. RISC is always extended to some new feature and suddenly becomes more complex. Meanwhile CISC is just a decoder over a RISC processor. Either way you get the best of both worlds: simple hardware (the RISC internals and CSIC instructions that do what you need.

Don't get too carried away in the above, x86 is still a lot more complex than ARM or RISC-V. However the complexity is only a tiny part of a CPU and so it doesn't matter.

You seem to be confusing ISA and microarchitecture.

Modern ISAs try really hard to be independent from microarchitecture.
