Except for the poly neck feel that you should take care of and personally frets polishing I would not touch anything else. When it comes to Fender aged, patina, beat up equal more $$$.
Speaking of which can you show us more pictures front and back? This will be very educational for most of us and if you ever take your neck off be sure to take the pictures of the stamps and date,. On the neck and neck pockets. It would be a great reference and future research for others.
As you may have remembered I scored a 2001 reissue 75 MIA jazz neck brand new( not lightly used) condition. While that is a unique conversation starter on it one but it’s nothing compares to an aged well preserved Fender neck.
Best quick and easy tool for fret polishing is this. I have quite a few, some are really awesome but nothing is as convenient.
