I use Trello for a lot of stuff. Shopping lists, to-do lists, keeping track of tasks needed for whatever home project I'm working on, and lately I've been doing it for work tasks since I'm juggling a lot of things with dependencies that come and go. Most of it relies on kanban boards, which basically means different columns and stuff in each. Work to-do list has a column for stuff I can/should be doing, stuff I'm blocked on, stuff that may need a little polishing but it's nearly complete, and stuff that's actually done (gives a little motivation). Shopping lists are separated by store. Stuff like that.
Unfortunately it's one of the subscription cloud apps... But their free version is very usable and hasn't been overly enshittified... Yet.
