Is there any strategy around getting things onto the market faster? Do particular governments have a faster time-to-market, or does it help using additional turns to put smaller amounts onto the market?

Its random between a min and max time govs dont have any impact.

What happens when I cut oil prices , dose it get sold faster if it under cuts the currant $300, a barrel ?

The lowest price will be displayed first so it will sell before the higher priced oil once it hits the market. Price has no impact on how long goods take to get to the market.

I sometimes recall immediately when I see that my goods take too long to the market. That is not viable for every strategy tho.

Luck is supposed to help but I think putting bonus points towards luck in Express is kinda silly.

send your goods exactly one second after a new turn appears to get minimum time to the market.

Thanks for the tip Marhsal!
