The Framework laptop the fox talks about is also a metal case. With captive screws and easily replaceable/upgradeable components - and several generations of upgrades already available to build trust that they really do intend to support that upgradeabiliy over time.
Org Mode.
I’m generally a vim user, but for job-related task management I set up emacs with evil (too many) years ago. There were vim plugins to reimplement pieces of it, but none of them covered all the functions I would use (that may have changed in the last decade, but I have a working system so it wasn’t worth the effort to check). I add tasks, tag priorities, and set recurrences for maintenance tasks. For billable or potentially billable tasks I use the built in clocking.
I make relevant notes under the tasks as I work on them, keep the finished task until weekly manager meetings, then archive them so they don’t clutter my working file but remain searchable if ever needed (which is more often than you might think).
I add new tasks at the top. Unfinished lower priority tasks get pushed down out of sight over time. When we hit a slow period, I review them and archive anything no longer relevant, then reprioritize and start working through the backlog.
