An ordinary thank-you can acknowledge work without turning it into a ceremony.

Gratitude that is too large can be as awkward as none at all. Making a speech about a small favour turns it into an event, and the person who did it now has to manage your feelings about their five minutes of effort. A plain thank-you does the whole job: the work was seen, it was appreciated, and nobody has to stand still for it.

Aim to be accurate rather than effusive this week. Name what the person actually did, say thank you, and move on. Save the larger version for the times when the effort was genuinely large, so that when you use it, it means something.
