We don't tend to recommend terrariums because they typically don't have drainage holes and they can lead to overheating roots because of the glass base.
However, because of their immense popularity, we have a section on our website dedicated to plants that tolerate terrariums well. We recommend checking that out by clicking the link below. This tray will contain lots of different plants, some tolerate terrariums and others do not.
As far as terrarium medium is concerned, you'll actually want a few layers of different mediums. The layer at the bottom of the terrarium should be pebbles or fine gravel. This gives a place for excess water to escape. The next layer should be thin and organic. Sphagnum moss is a good choice because it'll make your soil more acidic which succulents tend to like. More importantly, the moss will create a barrier between the layer above it and the rocks below it. It's better that these layers don't mix because that would defeat the purpose of giving the excess water a place to escape. The final layer should be a 1:1 ratio of bagged succulent soil and perlite. This layer should be the thickest as it is the layer you'll actually plant your succulents in.
Be very careful about watering a terrarium, being sure to water only once the soil is completely dry.
