In for a penny, in for a pound, eh?
The pano roof does help for forward headroom as well as aft. I'd be in trouble without the additional clearance enabled by the pano. Plus I use coat hooks frequently.
If you're really into clean, accurate sound, consider a Reus Audio upgrade for that factory-upgraded audio. It transfers from car to car so it'll be the last set of components you buy. Ask for Cliff. Easy drive from the Bay Area, plus he'll quite probably be at TMC Connect and could bring the needful, as it were, presuming you're planning to attend in a few months.
Your car won't be ready in time for the Sound of Silence (3rd Annual Black Hills Tesla Rally) in late May, but do pencil it in for next year - it's an absolute must-do event, even if you don't stay at the Rocket Motel where Elon and family stayed, which, in conjunction with a proactive Chamber of Commerce and active Colorado/Wyoming owners clubs, is what started the whole thing. It's also an easy, superchargers all the way road trip, with proximity to more sightseeing than you'll be able to fit in (Mount Rushmore, Crazy Horse, multiple caves, Needles State Park, and so forth).
In other words, welcome to the club. Whether you do all or none of the above, there is clearly no better car on the planet. Nicely done.
