From a Progression perspective you have a couple of reasons to do a quest (aside from the fun/challenge): faction, coin, gear and/or experience. Most quests have been adjusted down over the years to not give much experience.
Good Experience: NOTE: Early in the Phinigel server era they have nerfed quest XP massively (90% off by some reports)... unclear if this nerf was to all servers or just progression servers. This means there may not really be any more "good experience" quests on progression...
Crushbone Belts (good XP well into teen levels, gives patchwork armor)
Crushbone Shoulder Pads (better XP than Crushbone belts)
Red Wine in Neriak (decent XP at level 5 --note a week later from when I last did it we are hearing it has been nerfed, so maybe just a faction quest now)
Fire Beetle Eyes in East Freeport (note same NPC does bone chips and spiderling silk which are both less XP)
Fire Beetle Eyes in Neriak (need faction with The Dead to do this, decent XP at 5)
Deathfist Slashed evil and Deathfist Slashed Good (nice that you can hand in singles)
Moonstones (Captain Tillin has a few quests, Moonstones involves gnoll teeth)
Gear and/or starter coin:
Bone chips in Kaladim (if you can't wear the gear, there is a merchant right by the quest NPC.)
Crush the Undead in South Qeynos (used to be good XP up to level 7? needs confirmed)
Spiderling Silks in GFay (gives newbie bards a drum, may be good XP?)
Red V Clockwork Also known as "Bullsmasher quest" in some sources (gives a variety of awards, sounds quite involved, need verification of factions and XP)
Lizard Tails in Ogguk (gives rawhide armor)
Going Postal (Kelethin to Freeport) is one example. Doing a search here of "going postal" should generate this list of 18 quests.
Scarab Breastplate ; Scarab Boots ; Scarab Helm (gives +to many Dwarve factions as well)

(It isn't great, but it's something if your race/class combo can wield it.)
Faction:
Batwings in Felwithe (need to be liked by high elf mage guild... I got my high elf cleric to level 3 with this quest, but I handed in nearly 200 bat wings to do so. My wood elf ranger didn't have the base faction to do the quest).
Bandages in Misty Thicket (may give XP at very low levels --needs confirmed, does build most Rivervale factions)
orc scalps in High Pass (captain Ashlan is up top on the bridge/ridge over the path in the south of Highpass, this quest may be good XP at low level but is not by level 10. It does give decent gold for the level)
