Wotcha and welcome. I always do a full service, gearbox and diff fluids plus spark plugs and a mini detail. That way I know a starting point for mechanical service and can check for sparkly oil contents and doing the mini detail (jet wash, snow foam, rinse, hand wash, dry, clay bar, polish and or wax) means I go over the car front to back and you get a good look over the body work, tyres etc.
I also replace windscreen wipers with PIAA items but that is a safety thing as they give improved visibility in the rain
