(just a general opinion about something you said and not a direct criticism of the good idea of using mental stats to assess things when you have the time to do some assessing beforehand).You can just move behind the door & hope for the best. Alternately if you were really stumped on what your PC might do you could make some kind of knowledge check (ie wis:stealth or wis:insight) to intuit what would be a good place to hide then say "yea I want to hide in [specific one]" after coming up with options. Of couirse how long you want to spend trying to intuit that will impact the DC & possible results but you would need to decide that not expect me the gm to decide it
I would expect deciding where to hide is a part, maybe a central part when in a hurry and needing to hide now!, of the Stealth skill. My real-life Stealth let me know that one can't hide by just running behind the back of a person and mimicking his moves, and that closing your eyes doesn't make you more stealthy. At the table, I'd be unhappy if my skilled rogue mastering the art of not being seen was having to roll (and potentially fail) because the untrained barbarian's player identified that hiding behind the curtain was the ideal place (automatic success) while I chose to have my rogue hide under the table.
Same if I were to use Stealth to get past a guard. It might very well be extremely stupid in real life to throw a rock at an armour to make a noise and use the time he's looking toward the noise to speed toward the next room, because it warns the guard that something is odd and he probably won't leave his post to look at the armour scratching his head but just glance quickly toward the armour and put his hand on his sword, warily (or it could be a tried and true tactics of infiltrators, for all I know, but let's assume it's bad). So basically, doing that is both a flourish in description and a bad idea that should warrant disadvantage, compared to Bobby Barbarian whose player just said "I roll Stealth to get in the next room, err, stealthily?". I'd say my skilled rogue would know if the stone trick is a valid one or not. Especially since, irrespective of the validity of the trick in real life, it works in fiction (Plague's Tale, Thief...) and might work in the genre-emulating gameworld.
I am not pleading for not describing rolls, but that part of the skill is knowing how to do things without player adjudication. One wouldn't ask "do you chant the song of revealing first or do you do the magic-detecting gesture first when using Arcana to assess if the sword is magical?"
