Sorry for the confusion but I just gave a list of VFM products for around 1k.

Also it is difficult to suggest a single product because results may differ on weather conditions, application, maintenance & etc.
For a car that hasn't been detailed, we should start with polish (i.e Megs UP) then protect it with sealant and/or wax. AIO (Polish+Protect) are also good for beginners because full detailing requires lots time and energy.
As of Collinite 840, Sonus Paintwork Cleanser and other pre-wax cleaners; these are useful when the paint is in good condition or already detailed and you just need to remove any previous wax along with above surface contamination. It can also be used between polish and wax but it is not a replacement for polish.
For full detailing: Clay -> Megs UP or Poorboys Professional Polish -> Megs Nxt Tech Wax or Megs Yellow Wax or C845 or Poorboys EX Sealant or Poorboys EX-P Sealant or FinishKare Hi temp Wax -> Another coat of wax/sealant if you wish.
For quick detailing: Megs White Wax, FinishKare Ultra Polymer Sealant, Poorboy Polish with Sealant, Poorboys Polish With Carnauba or any AIO products that contain polish+wax. No need to use standalone polish or pre-wax cleaners before any of these.
