I don't really understand the question.
First of all, not all crops or plants are suitable for hydroponic culture. Long crops, root crops, low value crops, are not economically suitable. also because of the space constraints vining crops and crops that need large spaces are less economical to grow.

Some hydro systems are more suitable for different kinds of crops. You can grow carrots, beets, and onions, in a biofilter, but it is is not practical to grow these in a rail system. Rail systems are better for leafy greens with maturity of around 30 days.
Taro can be grown in a biofilter since the plant is semi aquatic anyway, but it is a long crop with an extensive root system that easily clogs the bed.
Kratky is practical for small scale hydroponics especially when there is not easy access to electricity or you are just starting out and want to keep cost down. Kratky systems are relatively easy to build and don't require pumps, aeration is optional. DWC systems differ from Kratky because they do use pumps. In terms of redundancy DWC,Kratky would be suitable for similar crops, so they would be the most redundant.
Aero towers and rails also are similar in terms of what they are capable of growing and how it operates. The main difference is one is horizontal and the other is vertical, so they do have some reduncy as well.
If you want the most diversity of crops in a single system, then a biofilter can grow leafy greens, some root crops (beets, carrots), herbs, and leeks. Dutch buckets you can grow the larger plants like tomatoes, cucumbers, peppers.
All systems can be run by hydroponic or aquaponics. In aquaponics you may have to add additional nutrients that are unavailable. Like additional iron for lettuce. In the biofilters we also used sustain and bone meal to feed plants.
