Inrush current limiting is achived by series resistance before caps, advanced would be ntc.
Keep in mind that battery, connectors, traces/wires, components in series will all add their series resistance and the cap has esr that adds too - this is not implicitly given in simulation.

As you have already a mosfet for reverse protection, you could go for one with the appropriate on resistance.
