I called LOT customer service, and was told that it is possible to change this ticket to another route, but only to an European route, as intercontinental routes have different tariffs, and its not possible to rebook an intra-European route to an intercontinental route or vice versa.
The 65 EUR change fee is paid only once even if both outgoing and incoming flights are changed, and indeed if I am changing from a STANDARD to a FLEX fare, no penalty is charged at all, so I now changed the ticket to a FLEX ticket almost a year forward paying just 5 EUR fare difference, and I think I will then be able to change for free to another route if I decide to fly somewhere intra-Europe during this time.
Also note, that at first the agent told me its not possible to change the route (without even knowing I want to change it to an intercontinental one), so I asked him again to confirm, and then he put me on hold to check something and then told me that yes, its actually possible to change the route, so then I told him I want to change to an intercontinental one, he didn't tell me its a problem, but transferred me to a cashier, who then told me its impossible to change to an intercontinental route. So it seems the call centre agents don't know very well, and if one tells you no, it can help to ask again or even call another time. Or maybe agents are taught to tell no at first, and only allow changing route if the customer insists.
This seems to be a nice loophole that makes a STANDARD ticket practically changeable without penalty. However on the new ticket, there is an annotation about an amount paid originally being non-refundable, so despite it being now a FLEX ticket (with FLEX fares having refunds possible), its not possible to obtain a refund, just change to another intra-European flight.
The date of the new flight must be not later then 12 months from the original ticket purchase date, not from the original date of the flight.
