I want to upgrade my retro game setup from a mix of composite and RF to a mix of S-video and component, with some composite for the really old stuff that doesn't support S-video. How can I distinguish the high quality cables and switch boxes from the low quality stuff? What physical properties make these cables and switches better than others?

Unfortunately it's mostly about the internal fit and finish -- there's not much you can tell from the external look, or from marketing bombast.

How many insertion cycles is the product rated for? How tough is the outer jacket? How good is the strain relief? If the cables will be visible, then it would be very reasonable to choose them based on having an appealing appearance. Cables should either meet an industry specification, or have full engineering data published. Otherwise it is impossible to judge the quality of the cables (well, maybe you can judge quality based on a large number of reviews).

IMHO the integrity of the shielding is what matters. Without shields, RFI and EMI and black-brick switching-requlator spikes are aggressors into and onto the audio.
Foil may be best, but foil is fragile.
Thus multi-layer woven copper-braid shields should be your goal.
Been working with a guy on piezo-sensors, located a couple meters from the signal conditioning analog-circuitry. He uses 16KHz LPF into buffers, and then 5KHz LPF into the ADC sampling Vin, with that final large capacitor providing the ADC sampling surges.
His usual noise floor, using a 60Hz nulling algorithm to reduce/remove power-line electric fields, is about 1/2 a quanta of 4,096 levels with 0/3.3 volt ADC range.
Thus the RMS is 3.3/8192 or about 400 microVolts RMS, with 2 meters of shielded cable between sensors and analog circuitry.
The "laboratory environment" includes numerous black-brick power supplies, and some unused old computers with metal cases that show 180 degree phase-shift of the 60Hz; a DVM shows 200+ volts between these unused computers and the analog circuitry/sensor returns.
Forgot --- here are several 2Ghz and 5GHz Internet Routers, about 6 feet away. I've carefully encouraged use of passive RC LPFs (15KHz and 5KHz) to reduce high frequency energy into the opamp buffer which might overload input-diffpair isolation-diode junctions; for these LPF's to be effective, the impedance of the LPF's shunt element, the capacitor, has to be low inductance with the capacitor's RTN node tightly wired to input-signal's RTN as well as the output (filtered) signal's RTN).
Thus a comprehensive approach to protecting your audio signal cleanliness is your task:
1) cabling
2) cable connectors to/from the circuitry
3) filtering
4) proper use (skilled use) of mechanical structures (planes and cases) to ensure the interference must attempt to pass thru filters, and not be easily routed around the filters
