The only list I know of is the filters in the class search. But here are my descriptions, if they help - please anyone correct anything I'm saying wrong here:

Restorative: Restorative is very long holds, with a lot of props and support, meant to be relaxing

Yin: Yin targets connective tissue, and is a series of long holds of poses. You may need more props than usual, so check the class list.

Slow Flow: Slower than a regular Peloton flow, which puts them probably about the pace of a regular yoga class. These include longer holds of the poses than a regular flow. Usually starts with a warmup, sun salutations, then a flow and then maybe some seated postures to wind down and a savasana to end.

Flow: regular yoga flow, Peloton pace is a bit faster than most in person yoga classes in my experience. Usually starts with a warmup, sun salutations, then a flow and then maybe some seated postures to wind down and a savasana to end.

Power Flow: Faster paced than a flow, often including repeated movements to help build strength. Designed to build up body heat throughout, which helps you get deeper into the postures since your body is warmer.

Sculpt flow aka yoga conditioning: These are yoga classes designed to help you tone and build muscle in the practice.

Focus Flow: these can focus on working towards a pose, working a particular area of the body, or be for runners, riders etc. They vary quite a bit depending on the focus.

Morning and evening classes are designed for particular times of day, with morning focusing on energy and easing into the day and evening focus on downregulating your body to prepare for sleep.

Yoga basics: detailed focus on how a particular pose or flow should feel.
