Its a cantrip. They can cast it before each and every skill check a party member makes (except in the middle of combat, then the action to cast the spell kicks in and limits it).
Rogue checks for trap. Guided.
Bard makes a performance. Guided.
Paladin questions a demon. Guided.
Ranger tracks a goat. Guided.
etc...
I see it more as a roleplaying opportunity for the cleric.
May Pelor guide your hands to keep us safe as you disarm this deadly trap.
By the grace of Pelor you shall perform your best tonight dear friend.
With the light of Pelor this demon shall hold nothing back from from you.
Pelor will provide may your efforts to feed us be blessed.
If you only ask for rolls when it matters, and not trivial tasks, guidance makes much more sense.
Don't forget anyone can use the help maneuver and give advantage on all those rolls as well, and that doesn't need a spell.
