High output MC make no sense, so it must be LOMC or MM/MI
I have no personal experience with Rega turntable, but cartridge must be selected for the tonearm, calculation is pretty easy if you know your cartridge compliance @ 10 Hz and tonearm effective mass.
I would recommend Victor X-1II mid compliance MM with rare Beryllium cantilever and Nude Shibata stylus tip. One of those amazing vintage MMs that you can't go wrong with. Superb sound quality if you're able to find NOS or MINT- sample. Ask if you need help.
