Getting into cEDH looking for a little help across a few areas

Hi all,

I have played magic since Mirrodin block on and off and came back after an extended break about a year ago and started playing commander. I have recently gone down the cEDH rabbit hole and am starting to really want to play more of it. There isn't a cEDH presence at my LGS so I want to start playing online. With that as the intro here are the questions

1. What is the better online platform for cEDH and B4 play?
2. In online platforms how much chat is needed? I will be playing in the evening and would prefer not to wake the kids/wife but can find a quiet spot, I am also not the most social human in the world :laughing:
3. For online set up is a laptop and an external cam enough?
4. I am looking to start with Kinnan and proxy it is there a more beginner friendly list? I would prefer to steer away from straight Rhystic copy, is big flips a better option?
5. Is there anything else I should be looking at? I spend a lot of time on YouTube watching content like playing with power and play to win. Are there other channels I should be looking at? I am not sure if I will venture into actual tournaments at the moment and may even look at hosting ones at my LGS if I can talk them into it as I used to run and judge other TCG's years back when I used to work in a LGS

Thanks :smile:
