Welcome!
If it runs well, yeah man, I’d just clean the heck out of the engine bay and undercarriage, change all the fluids, do a simple tune up, bleed/flush the brakes and either replace or pack a spare fuel pump and drive the heck out of it.
While I’m not a big “patina” fan in general, a truck like yours that is truly original paint and not beat up, it looks sweet.
Refurbishing the interior is about as easy of a project as you can do. Most importantly, looks like all the painted surfaces look beautiful (roof, lower dash). Interior work is 90% wallet and 10% work.
Keep what you can, replace what needs refreshed. For around $1000 you can have a new OE quality dash pad, seat redone or do a new Oe style seat cover yourself, and new rubber floor or carpet and maybe new door panels.
Dash pad is about 1 hour to replace, door panels an hour a side. Half day to remove the seat and redo the floor and another day to take apart and recover the seat or however long and however many $ it takes to drop it at an upholsterer.
You may find you want to “restore” some of the parts, read up on here about re-painting parts like the heater vents or dash bezel or door panels. Can save a few hundred bucks and have a nice end product that you restored yourself.
And worst case you don’t like how something turned out, you don’t have any $ into it and you can always buy a new part instead.
Exterior, there’s some methods to shine up and “preserve” what you have.
I’d sand and re-paint the rims, easy, cheap just takes some time and elbow grease. Re-furb the hubcaps, fresh tires and it’ll look sweet!
Sorry, I just layed out my plan for that truck if it was in my shed and not yours! Lol
