Why does a IRFP460 turning off an LED Strip but a IRLZ44N or IRL540N can't?

The IRLZ44 is specified for 50A loads, and your load (0.042A) isn't anywhere near that. The use of a low-power switch FET will help, or you could use a bipolar NPN transistor instead of a FET. The ...

What approach do you use to connect SM JST connectors from led strips to a PCB?

The JST SM connector is exclusively a wire-to-wire connector with crimp terminals. Therefore, it does not have any solderable family members. If you want a wire-to-board connector, then use a wire-to-...
