Shorter runways require correct flying, whereas the long runways don't, absolutely.
Full points on the priorities, not so much about the touchdown zone. Although we say the touch-down zone is the first 1/3 or 3000 ft (shorter of), it is not how the aeroplane should be landed.
Touching down at 3000 ft (1000 meters ffs!) on a 9000 runway is NOT ok. To keep the performance data valid the ILS receiver passes the THR at 50', going for 955 ft (291m) intersect point against the pavement. The normal touchdown ensues around 450 m (1500 ft), anything beyond 600 m is not correctly done. Irrespective of runway length. Sure, we've all done it multiple times and nothing was compromised but it is not playing by the rules.
Somewhere in Germany - pure ICAO Annex 14 standard for runways 1500-2399 m. Four distance markers.
LDA 2180 m of which 1/3 is 730. 5x markers would be appropriate to show the 1/3rd "touchdown" zone.
