I'm in exact position as of you. Though I am looking for Product Management position.

Small Context:-
Apart from things you listed above, I have experience in Ethical hacking and data analytics as well. Built many products, some good , some bad. Helped many people (freely) to build their product and their internal engineering infrastructure for facilitating other developers to contribute smoothly.
On Business side, I'm strong in crafting various monetization strategies and know that I'm pretty good at predicting the market trend and reflecting things in my product roadmap. So, I figured it our that best way to keep me motivated and contribute in a significant way WAS to get into product management. Be it as general product management or Technical one.
I just don't have superficial knowledge, like know the interface of products and stuff... but literally enjoy to dwell into the core implementation of products/softwares which enables me to think from top of the stack to all the way to below underlying NAND registers. It's not like I had mastered every layer in between but I have enough enthusiasm to understand the WHY behind everything. This applies to both my technical and non-technical stuff.

BUT being said that, I have noticed that people generally don't believe in what we write on our resume/website. Because they feel that this guy is certainly bluffing. One thing I noticed though, whenever I meet someone in person, they instantly notice the difference. And they tend to seek knowledge from us. But again here my shyness kicks in I can't ask them for job directly. Can't even start a conversation, feels really odd. If you can try some offline aproach and are good with initiating conversation with people, you might find yourself better opportunities.

Why I failed in my startup?
Answer - I specifically lack in Sales. I'm introvert. And my major failure is that I didn't hired or had resources to hire a proper sales team. Ideally, I'm fully aware and believe that founders should be a good salesman as well, but I'm now learning to do that.

My Advice for you-
Brainstorm a little bit, imagine a situation where one founder gave you full liberty to help him for his product. Where will you will help him the most and at the same time will also enjoy for yourself. For me, it was Product management. I somehow feel the same for you BUT please spend some time to think on it. Once, your somewhat zeroed on your position, second step is to check the job descriptions of that position. Check 2 things there, 1) Does those job responsibilities excites you? 2) Do you have most of the "requirements" mention there. By requirements I want you to focus on the "skills / knowledge areas" mentioned there. If these 2 things resonate with you, you'll instantly know that where you fit the most. If somewhere things like "experience years" seems to be a hurdle, don't get discouraged. Still reach out to the recruiter and help them understand that you really know your shit and well experienced to handle the job swiftly.

Other Stuff-

Let me share one irony with you. While working on my startup, I gave chance to people just because they had enthusiasm and adaptability. They had literally zero knowledge in computer world. I on-boarded them, taught them programming right from some basic concepts of versioning to all the way to deploying and managing servers using docker or even VM based approach. Many of them got a job somewhere after working with me. But I feel pained about the same thing, I had not yet came across same people like me who believe in giving chances to people based on their enthusiasm and willingness. But I still believe that I need to find more of such people, who truly believe in a caliber of person. For them, a person is more important than the piece of paper.
