Someone with a little more knowledge will come along im sure, but a compressor seems like a good choice. It will level out everything.
Other than that, just use your ears and your hands. Those are your best effects imo.

This ^.
Left to my own devices, I sound louder with a pick but that's partly because I have so much more attack and I'm therefore more audible. Whether or not I'm actually "louder" is debatable.
I've just joined a new band where I have to switch from fingerstyle to pick and back again repeatedly within each set. For the first time in years, I'm running through an always-on compressor pedal, which I'm using as much as a Limiter as a Compressor.
