LWRP doesn’t have any advanced lights. The lightweight pipeline is there to be performant and these new lights in realtime have a cost to render. One Area light without shadows is two times the cost of a regular spotlight in HDRP, if you want to try the new fancy lights you will have to use the HDRP.
The new light types and shapes are
Spot
Cone - Regular/Default Shape
Pyramid - New
Box - New
Rectangle - Realtime Area Light
Line - Realtime, similar to Rectangle/Area Light but just a line
In the lightweight Pipeline, you still have Area Lights but you have to bake them just like the Default Render Pipeline
Currently, only One realtime Light can be enabled in a scene so you will mostly be using baked lighting. There was a mention of multiple shadow casting lights from a Unity Dev on the SRP team. Take a look at the post and thread for more details
