I agree with Paul about the types. There are a couple main categories: pitchers and no pitchers. I'll assume you want tropicals (as to avoid dormancy), so I'll recommend a couple.
N. Ventricosa, N. Copelandii, N. Truncata, and most hybrids of these. These are all tropical pitchers (nepenthes) and are easy growers. IME, these don't need a terrarium. Just good light/substrate and lots of pure water.
Sundews: D. Adelae, D. Scorpiodes, Most of the sundews you'll find online will be very easy to care for. These two are just my favorites.
The biggest things to consider are temperature: some plants (mostly highland neps) need a temperature drop at night. I'm finding that a little difficult to provide regularly atm. Some plants are less tolerant to extremes than others. Light: 5000-6500k fluorescent lights... basically as many lumens as you can get for most plants. Water: needs to be as pure as possible TDS wise. Distilled water is 0 TDS. I've also heard the 100ppm guideline, but if you're on that side you want to water more often and drench the pots. It has to do with how the minerals in the water dry on the roots if it doesn't get soaked thoroughly. In terms of water as well, there are plants that like to sit in a tray of water, and others that need to be well drained.
Truth be told, it sounds intensive, but if you know a few basic details about the plant it's pretty easy to meet the requirements. Which way do you want to go?
