I understand that the RF-related Simulink blocks were originally referred to as the “SimRF”. With R2017a, these blocks were replaced by the RF Blockset library. I would like to have an explanation of the differences between RF Blockset and the older SimRF.

Idealized baseband mixer has built-in frequency-dependent phase noise. It might be simpler to use for a single-frequency system with a known phase noise model.
Equivalent Baseband mixer is more general, because it allows the arbitrary oscillator signal (see, for example, the phase noise block in the 'simrf_low_if' demo). The "phase noise" block is used as a noisy oscillator to the two mixers in Hartley Receiver.
With respect to circuit envelope mixer, the closest demo which will explain more is 'simrf_friis'. There you can see the simple chain, where the signal is downconverted by a mixer and a noiseless oscillator.
Idealized baseband mixer would be more suited with respect to single frequency system.
At a high level, RF Toolbox is used in MATLAB, and the primary use case of RF Toolbox is circuit analysis, while SimRF is used in Simulink, and the primary use case of SimRF is circuit simulation:
Analysis - Calculating the overall properties of a circuit theoretically. Determining the overall power gain or the calculating the equivalent impedance of a circuit are examples of circuit analysis.
Simulation - Determining the response of a circuit over time to some input. The final result is some time domain signal (or set of signals).
You can think of RF Toolbox as a product that adds RF analysis functions to the MATLAB library, and the SimRF product builds upon this foundation to extend that capability to time domain simulation.
