Dutch tanks focus on the plants, so you would be limiting your fish options by going that route.
Dutch tanks primarily use stem plants, so if you went that route, I don't think any enriched substrate would be neccesary. (ADA Aquasoil or any high CEC substrate could have the benefit of absorbing excess nutrients and releasing them gradually. Products like turface pro, soil master select, etc sold at sporting stores work well.)
It would require a lot of maintenance (trimming, fertilising, massive water changes) and the livestock would ideally be limited to a single shoal of 10-15 tetras and/or small shrimp species)
I aquascaped a dutch tank back when I had a (short-lived) job as an aquascape designer. For the "dutch appearance", even warm colored bulbs 2000k-4500k can work. The EI (estimative index) fertilisation method will limit algae on it's own. (3 days a week dose macros, 3 days a week dose micros, and one say a week don't dose, and instead do a massive 80-90% water change)
You will need CO2 supplementation, preferably from a pressurized tank.
If you need any help, pm me and I'll post here.
