From a few videos, and some Amazon searching, it looks like these are the following replacement parts for interior and license plate LEDs - if someone could validate, it would be appreciated:
License plate: 2 x festoon 36mm
Frunk & Trunk: 2 x 41mm festoon
Lower doors and map light: 3 x T10
Glovebox: 1 x festoon 31mm (some say 36mm, some say 29mm - would love if someone knows for sure)
I was looking just buying the Sylvanias off Amazon, unless anyone has other ideas.
