Wrapping my head around MC carts. HELP!!!

So, I recently took a head first dive into rebuilding my hi-fi system, and have been quite pleased with the results.  I picked up a Pro-Ject Debut Carbon Espirit with the Ortofon 2m Blue cart, a Vincent Pho 700 pre, and a Jolida JD301BRC.  So far, haven't been disappointed.   But I've been bitten by the bug by all of this, and have been researching and trying to understand cartridge compatibility, in terms of compliance with the tone arm, and the output matching  with my preamp.  Specifically with MC carts. It seems to be going over my head. All I've been able to figure out is that the tonearm on this deck is 6g, and the input impedance of my preamp is 100 ohm, on the MC setting.

Was hoping to maybe get some elaboration on how this effects what I'd be able to use with good results in my set up,  or recommendations in the <$600 range that would suit this setup. I've found online resources, but still ended up with more questions than I went in with! Thanks in advance!
