I tried the egg carton thing, it was a waste of effort.
From Home Despot the best option was the germinating trays that allow you to germinate 40-50 seeds at once. And water them all at once. And put a light on top. And depending a heat pad underneath.
Put 2 or 3 seeds in each, cull the smaller ones, this allows for duds that don't germinate. Use some decent liquid fertilizer in the tray of water.
Once the roots poke through the bottom start transplanting them to small flower pots. Depending on where you live you can move them inside/outside/inside to harden the plants in cool climes.
If you are going to over winter any plant (frost is death) plant them in 5 gallon pots.
I never have grown any of the varieties you have mentioned so try them and learn what and how they do. I like the super hots, Morugas, Chaguanas, etc. They take a long time to germinate (60 days or so, or more) so I really started them in the fall to plant the next spring.
I bought my seeds at Pepper Joe, great variety.
