If you haven’t tried it you should check out Sunsama. I have tried a lot of todo apps and have never found one that works for every situation and Sunsama kinda solves this through integrations. I really like that it connects to email and other calendars as well as apps like Trello and Jira and lets me track them all as cards and even automate what happens when I mark them done in Sunsama. It also supports tasks directly and I use those for a few recurring tasks that don’t fit anywhere else. ADHD wise it has been helpful with planning times for specific tasks and seeing how they fit into my combined calendars and get better at time estimating which I didn’t expect. I think it’s general “turn a week into a kanban board” concept took some getting used to but it has been really helpful for me as well. I anecdotally feel like I get more done and am less overwhelmed when I keep to the daily ceremonies that it has as well for what it’s worth.
