Grounded is the "easiest" to complete if you're okay with acquiring an up-to-date save from another player who has already completed the game, including the most recent title updates. However, if any future title updates are added, they would require you to complete them on your own or wait until all title updates have been released and acquire a saved game from another player.

Otherwise, Unpacking is the easiest to complete, and it's a laid-back game, so it can potentially help to reduce mental stress.

Good list from Marzmitts. Also I recommend going on trueachivments. Then using there seach fucition to find the shortest time to beat game and games with most completion percentage.

Gang Beasts is pretty short, but you may need a second controller or boosting partner.

Easiest or "Fastest?"

Fallout 4 is easy to complete. Just play the game and explore everything...

Thanks for the suggestions. I went with Unpacking since it was short time wise and it had no DLCs

Inside was fun and easy

Firewatch is also an extremely easy and fast completion.

I haven't played Unpacking, I think from what I remember seeing is that it's an easy and quick completion.
Gang Beasts, Hellblade, Inside
All 3 are easy and not that long to complete. Inside maybe 2-3 hours, Gang Beasts 3-4, Hellblade 4-5

Firewatch is also an extremely easy and fast completion.

Playing through Firewatch was a unique experience.

Vampire Survivor is not that hard but it requires quite a bit of grind... so I would not recommend that for a quick completion.
