Cartridge Loading- Low output M/C

I have a Plinius Koru- Here are ADJUSTABLE LOADS-
47k ohms, 22k ohms, 1k ohms, 470 ohms, 220 ohms, 100 ohms, 47 ohms, 22 ohms

I'm about to buy an Ortofon Cadenza Bronze that recommends loading at 50-200 ohms

Will 47 ohms work? Or should I start out at 100 ohms?

I'm obviously not well versed in this...and would love all the help I can get.

Also is there any advantage to buying a phono cartridge that loads exactly where the manufacturer recommends?

Any and all help would be greatly appreciated.

Thanks in advance.
