Yeah for sure, I always drill a clearance hole, rather than a pilot hole when screwing anything down. If I’m adding a batten to a wall, I want the hole in the batten to be a bigger diameter than the thread of the screw. The head of the screw will provide the holding power, and the screw will clamp the batten to the wall much better if none of the thread has engaged in the piece you’re attaching.
A very simple thing that is often overlooked or misunderstood. Having a clearance hole also gives you the minor adjustment you talk about. Get it half tight and tap with a hammer until level and then fully tighten.I’m preaching to the converted, but it’s always worth saying.

If you assume the drill bit will wander a little,
you need a little built in adjustment.
For stuff that no-one will see, (slightly) oversize holes through the baton,
and a penny washer under the screwhead to hide any 'up & down',
and to spread the holding force.
