phono cartridge help

Hope everyone is doing good. It was a cold one here in NH Saturday, So I had some indoor time and was looking to replace my cartridge. My head started spinning with everything that came into play with compliance, Capacitance, stylus type, output voltage and my limited options.

What affect would I get going from an output of 5.5 to a 4.0 or to a 6.5mV?

Turntable is a fixed 20 vta am I stuck with a 20 vta cartridge?

Opinions on these:  

Prestige 3 Series  

Audio-Technica VM740ML  (0.5 g over limit)

Nagaoka MP- 200

Goldring 1006 vta 24

With what I have now it is very limited to upgrades but I'm not ready to spend the money on a proper phono system, in 2 or 3 years.

I listen to Yes, Stevie Nicks, Tom Petty, Eddie money, steely dan, David Bowie, the Cars, Rickie Lee Jones, Traffic, the Who, Savoy Brown, Van Halen.

What I have:

I clean my records with an ultrasonic cleaner and anti-static brush, I would grade my records at vg/vg+
