I wonder also if you're going to love the glass canopy in Texas sun and heat. I drove both a glass canopy and metal roof locally here before deciding that the metal roof was my preferred choice, even if they had been the same price... a nice bonus was the big cost savings on the metal.
For me, having owned glass-roof Teslas, they do feel a little more "open" inside, and they have more of the "wow" factor for passengers, but not dramatically so... not enough to warrant the big increase in residual heat when driving and especially when parked (which will also affect your range as you may well need more A/C usage in the glass roof). And I live in temperate Northern California, so not that hot in the summer compared to Texas.
When i finally got the chance to drive the metal roof Touring before making my final choices, it didn't feel claustrophobic, and (OK, wading into controversy here) I really don't like the two-tone exterior look of the Air with the glass canopy. Much prefer the body-colored pillars and roof surrounds. However, I have a Zenith Red, which is dark, and the two-tone look is definitely more prominent on the darker colors and less offensive (to me) on the lighter colors like your light blue. Again, may be worth playing with the configurator to judge the exterior look for yourself on the two roofs if that matters much to you. Just something to consider...
