JW-7607 Dome Tent

I have used an ozark trail 3 person dome tent quite a lot with good experiences. Not very lightweight though, so car camping only.

The Walmart Ozark Trail 3 person dome tent is $30 and very light and ideal for Texas, although based on your requirement for space I would go for the 4 or up to 6 if you are fine with carrying more weight. I'm using the 3 person one for just me in Texas and I love it. It's only 5.64lbs and extremely spacious. I usually use it without the rain cover and only add it if there's high chances for rain. Any kind of more expensive tent seems completely unnecessary in your situation.

See if you have a Sierra store nearby. They are ran by the same folks that do TJ Maxx. They are basically an outdoor centric version of a TJ Maxx, with some incredible deals in the camping department. That being said, no need to go fully kitted straight out of the gate. Buy what you can, and upgrade/replace as you can or need to. I grew up camping, my wife did not. She wanted to try it, so I went out and bought a 3 person tent, a couple sleeping bags, and two chairs, all ozark trail brand, from walmart. I got a used coleman stove off of craigslist, and a few small pots and pans from a thrift store. With that, we camped for two seasons before we started replacing it with better kit.

I'll start by saying that we camp in the Catskills in a remote area with zero amenities or other campers around. My son started staying in his own tent around age 5 or 6, my aunt had given him an Ozark Trail, probably 2-3 person. His tent was reasonably close to ours, and the dogs slept with him, and I would give him the key fob to my truck, if he were scared or needed us in some way he knew how to use the "panic" button on the remote. He used that tent till the wheels fell off, until I bought him a small Kelty when he was like 17 I think. My daughter started sleeping on her own a little later, probably 7-8, but would switch between our tent and her big brother's for a couple years before that. But same for her, she got the dogs and the key fob and an inexpensive, well reviewed Amazon tent that got replaced in a year or two with a Kelty since since her first tent had gotten damaged, not by her.
