In that tank for plants i'd say any of these but you'll need to secure them to driftwood for a bit until their root system develops
Anubias hastifolia nigeria cameroon ziare ghana togo
Anubias afzelii (senegal,guiena,mali )
Anubias congensis (west africa, congo river)
Anubias nana (west africa, congo river)
Anubias lanceolata (west africa, congo river)
Anubias nana (west africa, congo river)
Anubias frazeri (west africa, congo river)
Anubias coffeeolia (west africa, congo river)
Anubias barteri (west africa, congo river)
Anubias giantea (west africa, liberia cameroon ivory coast)
Anubias heterophylla (senegal,cameroon)
Anubias pyaertii (senegal,cameroon)
Anubias gilletii (west africa)
You could also do floating plants (many of which grow faster)
You're going to have some very big fish which can be hard on plants,not on purpose but just going thru them hunting could uproot plants with poorly developed root system.
My main concern for your tank is the mix of bichirs and their eventual size differences
I can't recomend mixing smaller upper jaw species ie.senegals and delhezis with large lower jaw species-Anne
