Listen to Jazz?
I'm reading a great Jazz Encyclopedia I was given. SOOO many Jazz greats made their reputations in the 40’s, early 50’s. i.e. MONO LPs. The recording techniques of that era (not the 30’s) were darn good.
Early Classical, so much great stuff is MONO.
Playing MONO LPs with a true MONO Cartridge is definitely better, by a little or a heck of a lot. Lack of Noise, and distinction of individual instruments (not imaging, but clarity from other instruments).
Playing a Stereo Cartridge even if your Preamp has a Mono Mode: the cartridge will pick up any vertical movement: scuffs, surface dust, dirt in the grooves, very slight warps: then the preamp’s Mono Mode will DOUBLE the unwanted noise in both speakers.

Thus, quick change from Stereo Cartridge to Mono Cartridge?
I went thru a few phases until I realized, get a TT with TWO Tonearms, two cartridges ready to go!
In any listening session, play Stereo/Mono/Back to Stereo in seconds.
A single arm, with removable headshells and a few cartridges pre-mounted can work, but tracking force/anti-skate/arm height adjustments/verify azimuth each change is not easy or quick, certainly not instant.
I got too excited and added a 3rd arm, but now I have MC long arm; MC or MM rear arm, removable headshells (swap mine or my friends), and MC Mono 3rd arm left side.
You can find a TT that allows 2 or more Tonearms, start with one, add a second arm if you find the need, at least start with the capability.
And, IF single arm, a removable headshell.
