I wood suggest starting with nursery plants if you have not grown anything before.
Mint should be berry easy to grow indoors any smallish pot with some direct sunlight. Mint is a fairly resilient plant, so it should stand up to a bit of poor quality care. It has the potential to spread and choke out other plants. I wood not suggest planting it in a pot or planter with anything else.
Chilis will probably not grow well indoors without a strong grow light. You wood also need sufficient space and a large growing vessel. Pepper plants grow fairly substantial roots and require a lot of soil depth. Mine generally reach about a foot and a half down outdoors. There are tiny ornamental peppers intended for small spaces, but, as far as I know, they all produce lackluster fruits. Additionally, you wood need to pollinate the flowers by hand for an indoor chili to produce well. Chilis are self pollinating, but indoors there wood be no wind, insects, etc. to force the pollen to move around. Gently agitating the stems wood probably be good enough to force consistent pollination.
