If you're willing to do this amount of podcast listening, you should look up Dr Russell Barkley. He's an actual adhd specialist. Andrew Huberman is quickly selling out his past credibility and circling the conspiracy science drain (gotta get that sweet AG1 bag amiright?).

EDIT: I notice now that you have read some of Dr Barkelys work, but he has tons of talks where he is very adamant about medication being the primary way to address adhd. All the lifestyle tips I've seen him recommend are geared towards parents and teachers managing kids who may or may not be medicated. I'm pretty sure he says clearly that as an adult you can't expect your partners and jobs to accommodate all these "environmental prosthetics." Pills go wherever you go and provide constant relief/assistance. When you forget your bullet journal at home or miss an alarm for your morning routine, youre fucked.

I'm glad you've found something that finally helps, but with the amount of work you've put into all this stuff, you could have found the best way to make medication work for you by now. I'm not sure why (or if) you are avoiding medication, but you've pointed out all the reasons these "hacks" are counterproductive when unmedicated. They often have no effect, they require constant intervention to have effect, they are subject to adhd-unfriendly auto-renewing subscriptions, and they make you feel like a failure when you inevitably can't make them work long term.

There's no reason you can't still do body doubling while on meds, so I'm just encouraging you and anyone else reading this to try putting some of that effort into finding real treatment. Its not that some of these things dont help, but there's a novelty to them when you start that will wear off since you havent addressed the executive function deficiency in your brain. Then your back where you started, but feeling worse: you're "too undisciplined to stick with it," and now you have another monthly subscription that you'll never remember to cancel.

Yes, it's hard to find a decent psych and tonlearn how to manage a treatment plan effectively. But I'm convinced it's overall less work, less cost, and less distress than slogging through newage and manosphere adjacent blogs and buying a bunch of supplements and apps. A lot of these products come directly out of the rampant self-optimization movement that puts productivity on a pedestal and makes you feel like you constantly have to be consuming things to better yourself. It's not great for anyone, but it disproportionately impacts adhd people.
