If you have money to burn, get some LEMO push-pull connectors. They'll run you about $80 for a pair of each gender, but when you use them, you understand why trendy audio gear and instrumentation/optical OEMs use them. Occasionally when I make a project I treat myself and use them. Cheaper options are Mini XLR and Hirose HR10. Molex make a lot of wire-wire, but they're typically not rated for more than 25-50 cycles.

Those magnet couplings are nice. EDAC make a non-Aliexpress version, about $25 a pair.
