I used to get sucked into finding new tools to help me be more productive, but keeping it simple and visible works for me.

Ditto! I keep my shopping list in Home Assistant, and always in Home Assistant. The rest of the notes go in Joplin.

I require apps that can sync (and at least work half-decent on mobile) and that are as little of a barrier as possible. Even then, forming a habit took a while.

The absolute memest.

It's so unfortunate that Firefox on Android, for some reason, never worked well with password managers (as I understand it, it doesn't support the APIs that Android has for them). Sometimes it'll trigger the manager, more often, it won't. Infuriating and a deal breaker for me.

I'll give it another go, maybe this has been improved recently.

Edit gave it another crack, gosh, it actually works now!

OpenSUSE, Tumbleweed on workstations (KDE) and Leap on my server.
