Sounds to me like you already answered your own question. It also sounds like you might be second guessing yourself and need some reassurance. That's alright, we're only human. If I were you, I'd take a good long break. Regroup for a third of it and relax. Then do some solo tinkering and see if anything gets you excited. Maybe you'll want to go another round with a new business at that point, maybe not. Join another team only if you think you can handle not being the top dog. Make sure that whatever position you get, you're happy with the amount of control you have while still keeping in mind that this is someone else's baby you're caring for now. If all that's a good fit and agreeable then continue on that path. If not, do your own thing. As for being type-cast as Engineer-Only, well, it's tricky... maybe you should leave out the part where you know how to code. You don't have to tell people you're a programmer right away. Get into the area of the business you'd like most before mentioning your other skills. Definitely mention your other skills, just not right off the bat. Other than that I'd say congratulations, you seem like you're doing very well and have luxuries that a lot of us (me too) are striving for. It's awesome to see people like you who want to keep going round after round in entrepreneurship. Its people like you who prove that when you something out of love, not money, you truly succeed. Hopefully I helped. Good luck to you!
