Well if you want plants start from the ground up. Plants should be fed at their roots as well as their leaves (even more so) so you're gonna need to choose a fertile substrate or add capsules to inert substrates to provide nourishment.
Some driftwood and pebbles etc are always nice additions to planted tanks to get that natural look and encourage natural behaviour from the livestock. An interesting piece of driftwood or tree stump/root is a must in my opinion. I'm not the greatest of scapers myself but you can get tons of ideas online and on here.
There should be a list of low light plants online and on here too. General you want to set the larger plants to the back of the tank with the smaller ones at the front.
You'll need a nice flow (but nothing crazy) so that nutrients, oxygen and heat can be distributed evenly around the tank. If you are not injecting co2
then Minimal surface agitation will avoid essential co2
from being lost to atmosphere.
Your lighting intensity is the most important aspect of lighting in my opinion and it is measured as par. Par changes with many things but mainly depth of the tank as low output lighting will be filtered out the further it travels.
Are you using carbon dioxide injection?
What is the height from bulb to substrate?
