Short-haul vs long-haul jet engine

Thank you for your posts.
Since it seems that turbine engines operate optimally at cruise (fuel efficiency), this will be beneficial for long-haul aircraft.
a-What about short-haul jets: how they will operate optimally since they have short cruise?
b-Since short-haul jets will fly daily more flights (compared to long-haul jets), does it mean that short-haul jet engine will have less MTBF (mean time between failure) or mean time to overhaul/maintenance?
c-If there is a trade-off between short and long-haul jet engine regarding fuel efficiency, reliability, maintenance cost,...how would a design of a short-haul jet engine will be different than the long-haul jet engine?
Your feedbacks are very appreciated. Thank you.
Regards
