ultimate stack for startup incorporation for bootstrapped solo founders? [I will not promote]

Hi guys, I'm hearing a lot of things: Stripe Atlas, Clerky, do it yourself, take a lawyer, etc. But I feel that most advices are for vc-backed startups and are just overkill for solo founders. What's your best recommendation for someone who wants to be solo and does not plan to raise? LLC? C-Corp? In Delaware? Elsewhere? I also realize there are a lot of administrative costs with filing stuff (e.g., California Franchise Tax, California Foreign Qualification, Registered Agents, etc.)—but also that most middlemen are making you pay a lot of money for absolutely no reason (basically you pay because you're too afraid of dealing with it yourself, but most things are not that complex, especially in the age of gpt) What tools do you use? incorporation, legal compliance, banking, payroll, taxes, etc. Would be great if we can put together an "ultimate guide for 2025"! Thanks for sharing! \[i will not promote\]
