An alignment check is a good idea.

Normally alignment techs also do a suspension check before alignment.

While it is up on the rack you can also do your own inspection to ease your mind.

Assuming it passes inspection and the tech starts reading alignment, any hidden damage should manifest in the readings.

I know the feeling, I gently hit the curb a few months ago while parallel parking and was concerned I may have knocked it out of alignment or damaged something.

Went in for an alignment myself and thankfully it was fine.
