First off, your car looks beautiful.
I worked for several years in a dealership body shop. First as a body man's helper, then as a painters helper, then as a painter. Having said that, I am NO EXPERT.
Taking your car down to bare metal is a very bad idea if you're not going to do a full restoration. The best/cheapest way to do it is to soft medium blast it clean. That process will F-up glass, rubber, plastic, so on and so forth. It also makes a terrible mess in nooks and crannies that you will find for years.
I believe your car was originally painted with lacquer. I imagine your repaint was lacquer also. Any decent body shop can prep/seal/prime your baby sufficiently to apply any pro finish. I would make absolutely sure you seal the original material coats before a new finish even if it's a new lacquer. Also, make sure that there are no spider web cracks in the current material or you will always have paint issues. Lacquers are not environmentally legal any more, but there are some 'old school' places that will still do it. Lacquer is really easy to buff, polish and shine for years with little degradation to the material. BC/CC is an option, but single stage sounds like the solution to your esthetic preference. Either material can be mixed with a 'flattening agent' to remove a little of the high shine. It's the same thing street rod guys use to create semi gloss paint jobs. One tenth (or less) of that quantity of flattening agent might give you your patina.
Another option... and please take it or leave it... is to take your fresh paint job, regardless of material, and do what the shop tells you not to do: drive it through a public car wash a few times before it fully cures. It's goofy, but if the paint is still "green" the brushes, wipers, sprayers, and towel dry kids at the end will 'patina'
a brand new paint job immediately. After that a fresh waxing and buffing will get her good and .... well... used!
Good luck out there. Their are no magic words. I would take a little time and talk to some old resto shops and hot rod shops in your area for some direction. When I say old, I mean old shops with old guys who snort out loud when you say "prius" or "environmental" and who are willing to look at an import. They are a dying breed but your answer is out there.
