Obviously depends on your cars history, and what access you have to that history?
I did oil pick up, and was a complete waste of money - FOR ME. If you have any doubts about service history/oil frequency/quality; do it. E.g. mine was on extended service as a company car (not mine!) from new, and that worried me.
also think about...
brake fluid change, including flushing ABS p/p unit with VCDS.
Air intake tract/ valves clean.
Rust proofing of vulnerable underside - got mine steamed off and "topped up" as some suspension components shoing rust at vulnerable edges.
Get your battery tested

Some of above is a bit of "future proofing" or maybe some sort of "investment", if you apply man maths?
