Take a look at your paint closely under the sun, you may see some swirls that need more than just a light cleaner to remove.
Of course, this is assuming that you have never machine polished your car (I am basing this assumption on your list of cleaners/polishes).
You can do very little by hand unless you spend hours and hours with a product like
scratchx.
Otherwise, based solely on your current selection, I would say autoglym SRP + collinite.
In my testing (as well as a few others) collinite will outlast
jetseal. Also, SRP has a combination of abrasives and fillers which is excellent for working by hand.
Don't let the 476's plain, old looking container fool you, collinite is one of the best carnauba products out there.
