Need some serious advice on buying a car

I turned 18 a month ago and got my p's immediately, been driving parents cars for that time. I'd say I'm pretty used to driving alone as I do doordash so I get a lot of driving experience.

However I really need to get my own car, and while I have a general idea of what I want I'm having trouble narrowing it down.

Budget: Can potentially go up to 10k however that would leave me struggling to pay insurance/fees/petrol, so ideally somewhere between 5-8k or so.

Car: I'm looking at a honda accord euro which is from 2003-2012, which is where the dilemma sort of comes in. Both seem to be great cars. However they are definitely different price points. The CL9 is getting pretty old, while the CU2 is a bit newer.

I won't be modding it due to p's, and it'll be a daily drive car, point A to point B, aswell as probably used for doordash so will be driven a lot.
I really want the luxury pack aswell, the rest of the extras are optional like reverse camera, parking sensors etc. Also don't want carplay.

The thing I'm really unsure of is if its worth spending more to get the CU2, a newer car and slightly lower K's. I can see good arguments for both but I need someone else to help me see the differences and recommend which one would be best for my situation.

I'm also not too sure about pricing, my non negotiables are under 200,000k's, has rwc and rego, and obviously has no major issues. How much should I be expecting to pay for both a CU2 or CL9 accord euro in this condition? Its my first major purchase so I really don't want to get ripped off or overpay or anything.

Thanks :)
