Since OP's friend only flies discounted Y, the best programs are probably the US-based programs (new UA or US) because they are the most generous with discounted Y tix (most are 100%). Not only that, these programs extend the expiration of existing miles with any activity, allowing accumulating of larger mile balances for premium award redemptions.
With regards to Y to C upgrades using miles, it would be pretty tough with any FFP if OP's friend continues to fly discounted Y since most *A upgrade eligible flights require higher fares (closer to full fare). Hope this helps.
