Wow, that's a great list! Sorry not to see Retail on the list, because my Cathedral is tagged retail (the high priest's household runs the church's gift shop selling lots of green stuff (my religion is about the green bars) and not the least wedding bouquets.)
Did not expect Gym and Spa, but it is certainly good for combo lots! Recreation centers might become my typical venue for funerals if they do not take place in a church. I'll have so much fun planning all this! :)
PS: It might be a good idea to make a basement, adding all relevant objects there and easily switch between weddings/funerals whatever, and maybe not all objects will be used every time. I just did that for the Ravenwood cemetery lot, and wheeee do I have lots of CC flowers ;)
PS2: I might also try to set a no-match lot temporarily to Generic, just for the funeral.
