I struggle with this for my personal computer. The TV-computer combo shuts off the monitor (triggers the tv to shut off when there is no input) after an hour. An hour after that it’s suspended, works well.
My personal computer though, sometimes I shut off the monitor, most of the time I let it run for the day completely powered. I have yet to set any type of shutdown or standby because typically I use it more than I do my tv (work, gaming, videos, etc on the comp). I know there’s some power conservation I need to consider for motivation, I have no security concern atm with my standard main account and everything private is layered so inaccessible.
tl;dr
what’s everyone else’s setup like for when they walk away from the computer?
Well, that’s me then.
Never know when I’m going to need it, and it’s usually doing some kind of work overnight (processing media files, syncing files around, etc).
I schedule that stuff for when I should be asleep - less heat in the house during the day, it’s off-peak power (doesn’t make a noticeable difference to my bill, but why not).
If i need it, I can pause those things.
But I also have a NAS that can do this stuff, but it can only do so much at once.
