I know Lufthansa offers you the upgrade as soon as you’ve bought the ticket (+ has bidding option). What about the rest?
Some airline options I have are: Lufthansa, Air France, KLM, Iberia, British
LH will offer you an opportunity to upgrade as you noted, purely from a capacity perspective LH operate B748 daily, so more seats available in business class, if you are able to chose the day of travel Googleflights would show you the cheapest days of the week for the J cabin.
