Your idea of a good landing, and mine, are quite different.
Basically, for a passenger (or cabin crew), the only factor that they use is the 'smoothness' of the landing. Fair enough given that's the only factor that they can actually see (or feel).
Within the coughpit, that's almost the last thing we grade it on.
As a generalisation, really smooth landings are done by extending the flare into a longer 'hold off'. That increases the risk of tail scrape, lengthens the overall landing distance, makes handling any crosswind much more difficult, and increases the likelihood of aquaplaning on a wet runway.
Some aircraft are also quite prone to sitting down pretty firmly. The 767 was renowned for firm arrivals, even though everything should have led to a smooth touchdown. The general theory for that related to the way the gear translated during the landing, and the spoiler actuation.
The are limits beyond which maintenance action is required. For the 747 and 767 there were two figures. 1.4 and 1.8g. Basically at the lower figure, a very quick look was all that was required, whilst the higher one required a visit to the hangar. The vast majority of landings, even ones you consider firm, are under 1.1g.
