Enabling teams can go work with other teams to "enable" them to be more effective. Think teams of specialists in skills that more teams need than you have specialists to go around, and who also benefit from the strong community of practice & extending state of the art with other specialists. e.g. Product security engineers. Enabling teams will work with all the other team types.

Complicated subsystem teams mostly work with value stream teams on a subset of a value "stream" that is complicated enough / specialised enough to need its own team of specialists, especially when it can be encapsulated in a library or service. e.g. owning an ML component within some software.

Platform Teams build an internal product and act like a value stream team where other internal teams are customers. Often useful for things that you wish you could buy off the shelf from a cloud vendor but can't. Building services and tooling that make the stream aligned and complicated subsystem teams more effective. Sometimes platform teams may need to act like enabling teams at times / with part of their effort to help other teams adopt their product.
