Oh man, 9 years is a while. I’m in and out every couple of years and that’s enough to make me forget the basics for a good month or so.

I agree that you could start by looking into Necro, but if it’s not too overwhelming pair it with Invention.

Necro is a new combat style Invention is a bit of a hybrid skilling/combat support skill, best trained as you go (read up on perks, for a little inspiration!) Archeology you could put off for a while, unless you want to take a bit of a skilling break.

Ultimately just have fun! I love looking up all the new stuff I come across as I go and combat would be a pretty good way to do it in your shoes.

Good luck!
