You can use any old addressable LED strip (WS2811, 2812B, 2813, 2815, SK6812) for this. The harder part will be routing the data lines correctly with so many different branches. You could always run branches in parallel if effects being duplicated is acceptable. I’d use your photo to route a linear path from start to finish. You can do multiple paths as an ESP32 or controller like the DigOcta can do up to 8 separate outputs. Then you can control it all via WLED (which includes a sunrise effect).
I dunno if lemmy has a WLED community but reddit has a pretty active one or you can use WLEDs native forums to ask more questions and get opinions from a group more focused toward the project you’re working on.
Also you might consider removing those two short branches in the lower left corner of the window by moving that peak a little more up and to the left to help simplify things.
