A lot of useful things have already been said, so I'll attempt to add value by asking a few questions that might be useful for you to ponder. I'll be as constructive and encouraging as I can.

1. You mentioned you were raised by a single mom - have you seen a healthy marriage before? Perhaps the marriage of close friend or relative? Right now, you have some image in your mind about what "falling in love" and "having a family" means. Where did this image come from? All of us are affected by TV and movies, of course, but, as an adult, you need to see real flesh-and-blood marriages, up-close. Find one or two couples you trust and respect and just ask, and they should be happy to let you in and help. Figure out how to answer this question - what does a good marriage look like to you?

2. More generally, it seems that you are in introspective person - lots of books, podcasts, therapy, exercise, apps. You've dated a lot. But it seems like it's solitary endeavor for you. Do you have close friends/family? Do you have someone you absolutely trust, who understands your life in enough detail that they can see through the "everything's great, how about you?" surface layer? Basically, it's tough to keep your own counsel, to be your own dating coach. You need someone else who can be a loving critic. Ideally, someone who is mature and relationally-successful.

3. We, as ego-protecting humans, have an incredible capacity for self-deception. Something isn't quite adding up. Given your qualities, your evident desire, and your extensive efforts - you should have been more successful they you currently are. Are you sure you're telling the whole story here? For example, some people deeply desire emotional intimacy, but become fearful when actual intimacy is within reach, because they can't bring themselves to show true vulnerability, and risk true rejection. Some people don't want to lose optionality, as, after all, marrying one person means losing out on the option of marrying anyone else. There's something missing here. You don't have to tell me, but it is important that you tell yourself.

4. While often unpleasant to think about, dating has a comparative, competitive aspect. At the very least, your competition will include 30-year-olds who resemble what you were like at 30. In what ways have your grown and become better than the 30-year-old you? What is your "competitive advantage"? And what kind of man will value and appreciate these qualities? Who is your "target audience"? Bluntly, what type of guy is going to pick you over the 30-year-old version of you?

5. Not a question, but I want to agree with comments encouraging you to look at "second-hand men". Basically, you missed the first bus, where all the conventional/normal people paired up between 25-35 years old. What's left are those who didn't get paired-up, or were paired-up but no longer are (divorced, widowed). You might have to go outside the apps, and maybe outside your usual circles in Austin to find them. Almost by definition, they will not be on the stereotypical life trajectory. In my mind, you're looking for someone who has been knocked down but has gotten back up, someone that life has already sanded away the rough edges. My aunt got married pretty late (40), and she found a chain-smoking, obese businessman who was working himself into an early grave. He quit smoking for her, started losing weight, and their two kids are now in college. He's a really cool guy, super funny and generous. How she saw that, back then, I don't know. Somehow I don't think the apps would have matched them.

6. Also not a question - but, if you haven't noticed, people in Texas tend to get married early, and Austin is a college town - there will be an endless supply of marriage-minded 20-year-old women there. Food for thought.

Good luck. And in case it matters, I am a happily-married Texan man with two kids, and, if you ever decide to convert to Christianity, I'd be happy to introduce you to an eligible (and slim and tall) doctor with a somewhat controlling mother.
