Tank is looking good! I was about to mention what looked like white ribbon in the first pic not being fully aquatic still I saw it's been removed.
Here is some more easy starter plants I have had first hand experience with and good results: water sprite, bacopa, wisteria, Cryptocoryne species(root tabs), Amazon swords(root tabs), star grass(not tried but heard good things about).
I believe with your light and some ferts you could do Staurogyne Repens as a foreground for your tank which would be cool. Just make sure your fish won't dig them up till they establish their roots.
Have you read up on root tabs? Root feeding species like Repens, Cryptocoryne species, and sword species need root tabs to get those extra nutrients. I've used Seachem root tabs with success or their is a much cheaper alternative on here: look up "Mebbid's DIY root tabs" it's a thread on here. Many have used them and are proven to work very well.
Have any ideas on the fish you want?
Hope this helps
