Fey touched gives you Hex or Hunter's Mark, which are both strong on a Monk.
Shadow touched gives you less that leverages your flurry of blows.
Elven Accuracy is triplevantage. Against an AC 25 foe, before you did:
4d10+20 on a 14+ (58% accuracy, 10% crit) for 26.6 DPR
4d10+20 on a 14+ (73% accuracy, 14% crit) for 33.7 DPR
On a 18 AC foe,
4d10+20 on a 7+ (91% accuracy, 10% crit) for 40.42 DPR
4d10+20 on a 7+ (97% accuracy, 14% crit) for 43.82 DPR
If you instead had Hex/HM
4d10+4d6+20 on a 14+ (58% accuracy, 10% crit) for 36.1 DPR
4d10+4d6+20 on a 7+ (91% accuracy, 10% crit) for 54.56 DPR
This is more DPR than the elven accuracy one, but this is (a) at the cost of a bonus action per target (ie half of your damage on a round, and (b) only for 1 hour/day, and (c) can be lost with concentration save failure.
But the DPR boost on "modestly high" AC foes is ridiculously good.
Note that if you had both
4d10+4d6+20 on a 14+ (73% accuracy, 14% crit) for 45.9 DPR
4d10+4d6+20 on a 7+ (97% accuracy, 14% crit) for 59.36 DPR
the swing is a bit larger. (but that is out of scope)
If you have something equivalent (flaming knuckles that grant you +2d6 damage on punches, for example), elven accuracy gains relative to Hex. (more damage per hit or crit improves EA more than it does Hex).
If you have a grappler in the party, they'll love Hex.
If counterspells are often an issue, Hex is also great (disadvantage their casting stat, which means if they have to roll to stop a spell they are in trouble).

Crusher is a near-guaranteed 5' move on anyone large or smaller, and about a 33% chance/round to grant everyone advantage.
Chef is 36 temporary HP and up to 10d8 short rest healing (spread out).
