Guarding Spirit and Actions with no target

[PiersonsMuppeteer]

Guarding Spirit on Yan Lo The Spirit Walker’s Reliquary says that Yan Lo can take a non-bonus Action targeting a model within 3” and LoS. Is Yan Lo able to take the Final Wishes action, or must the Action specify a target? If Yan is able to take Final Wishes, which range restriction would the trigger use?

The action has to specify a target, and that target has to be within 3" and line of sight of Yan Lo.  If an action doesn't talk about targeting, or use the word 'target', it doesn't have a target.  So you can't do it, just like you can't use Obey to make a Grave Golem use its Huge Fist action (Huge Fist has a trigger which names Mindless Zombie by name.)

If you were somehow able to take Final Wishes, that qualifier "targeting a model within 3" and LoS" would be irrelevant, because neither of those triggers are targeting anything.  Both of those triggers are choosing a model, not targeting one.
