I haven’t played or read enough PbtA to list a “favourite” move, but I like the Theorize move from Brindlewood Bay:

When the Mavens have an open, freewheeling discussion about the solution to a mystery based on the clues they have uncovered and reach a consensus, roll 2d6 plus the number of Clues found, minus the mystery’s complexity.
On a 10+, it’s the correct solution. The Keeper will provide an opportunity to take down the culprit or otherwise save the day.
On a 7-9, it’s the correct solution, but the Keeper will either add an unwelcome complication to the solution itself, or present a complicated or dangerous opportunity to take down the culprit and save the day.
On a 6-, the solution is incorrect, and the Keeper reacts.

I also like how that game’s Day and Night moves tweak the typical “Defy Danger” move.

I’m not familiar with the entire PbtA scene, but I found the Discern Realities podcast useful for getting my head around Dungeon World. It has some actual-play content, though it’s one-on-one duet play.

Yochai Gal’s One Shot World is a free Dungeon World hack that streamlines things a bit (not to the extreme extent of World of Dungeons) and provides some useful tools, prompts etc that the Dungeon World rulebook lacks. Stonetop is on my “to read” list though.

The last resource I’d suggest is 20 Dungeon Starters, which is a $5 PDF on DTRPG, though the product preview gives a good sense of what to expect. Essentially each dungeon starter is a double-sided A4/Letter page showing an appropriate amount of GM prep for a one-shot or beginning adventure of a campaign. A list of sensory impressions & situations, some custom moves and monsters, that sort of thing. The product page used to link to free versions of the starters, but DTRPG has helpfully stripped out the hrefs. This fandom wiki page has links to some of them, though some links are dead.
