First tank would look good with some congo tetras and/or rainbow fish. With the second tank, maybe go with some dwarf cichlids like apistogrammas or rams?
First tank a couple school of tetra, ember tetra for that tank would look nice, and a trio of dwarf cichlids. Second tank maybe some jewel cichlids and some congos. By the way I'm working on a 55 planted, where did u get your plants from?
You want fish stocking help? Oh boy do you have options
You can do the smaller cichlids like rams and such, angels can be a thing, small tetras and barbs, bristlenose plecos, shrimp, obviously not all in the same tank but you have options.
Think of things you'd like to try, then we can help you expand upon your ideas. What sort of livestock are you into?
