You have listed many fish on your wish list that are rarely discussed on AA. In particular:
African Leaf fish, Spotted Climbing Perch, Needle Nose Gar, Peacock Eel and the False Zebra Pleco. You have the potential to have a tank that is somewhat unique.
Full disclosure, I've not kept any of the listed fish, but I do have a little knowledge about them.
The Leaf fish, Climbing Perch and Gar are not semi-aggressive, but are true ambush predators. On the bright side they are cool looking fish that don't grow very big. Ambush predators don't usually tolorate
others of their own kind. I've seen tanks where several Gars were kept together. I'm definitely not your go to guy reference Eels, but believe the particular one you want is a good community species, that can grow relatively large. I believe the noted False Zebra Pleco is a typical wood knawer. It's a much better buy than the $200 it would take to buy a true Zebra.
There is a lot of space to fill in a 150 gal
. Tank. Other than the Eel, the other fish might only reach 6" - 8", and that might take 2 or 3 years. With a tank that size there are so many possible semi aggressive community combinations. Be sure to research South & Central American Cichlids, Large Tetras, Synodontis Catfish, Botia Loaches, ect. Good luck with your project.
