Business Lite also does not have the flexibility of Classic or Comfort fares. I honestly do not buy Lite because of this very reason. I would be keen on saving some money and not have lounge access (I can use the status longe and my connections are 2-3h) but the compromise on flexibility I am not accepting, so for me only Classic fares.

Tbh what I found most annoying (and little cost explanation behind it) is the seat selection for a fee (even for Classic fare). That one books a J ticket and needs to pay extra to reserve a seat is a bit too much of a low-cost approach.
