First of all welcome. It's great to have another Texas OB member! You aren't outnumbering the Florida members yet, but working on it!

Now that we have that out of the way....
You have probably one of the most perfect growing areas for most common-grown orchids that I have ever heard of. I dream of such a location.
Here are some choices based on a few basic requirements:
Reasonable humidity (above 40% most of time)
Most grocery store or Home Depot Phalenopsis hybrids (the ones with the long arching sprays of beautiful flowers) Here is an example
Most of the Paphs you are likely to see in the same vendor locations. They are sometimes refered to as slipper orchids because of their shape. Here is an example of what one looks like
Drier humidity (say 30-40%, maybe lower)
Intergeneric hybrids. These are hybrids of typically Brassias, Cattleyas, Oncidiums and perhaps Miltonia. These might not be so easy to find unless you go to an orchid growing greenhouse, but they are extremely easy to grow in your situation. Many are very nicely fragrant. Every once in a while, you can find some really beautiful intergenerics in a grocery store or big box store shelves. An example of the flowers is
or
It's a rather larger plant, though, and for most people only blooms once each year.
In short, there are many, many choices. I would strongly recommend not specializing when you first get started. Try lots of stuff. By selecting a cross-section from Phals and Paphs, for instance, you will end up with a longer period of blossoms. As you learn what really "turns-you-on" so to speak, then you can delve into different species and crosses, within that group, to extend the bloom season. Once you have it "dialed in" it's possible to have something in bloom nearly every month of the year. As your collection becomes larger, that scenario is more likely. Mine right now is not really large, but it seems like something is ready to bloom or in bloom just about every month.
