2005 Silverado 4x4 upper control arm advice

Stock ride height, 340k miles on it. Upper control arm bushings are shot. The plan is to put in new loaded control arms and bring it in for tyres and an alignment. Looking at the choices is making my head spin. My friend says he gets the adjustable so it’s easier for them to do an alignment. The price difference is pretty big. Am I shooting myself in the foot if I get regular oem ac delco non adjustable and bringing it in for alignment? I don’t know what it takes to align this thing. Thank you!
