I'd suggest the Krogan from Mass Effect, but with a Catachan flavor. In Mass Effect they already grew up on a Death World, so it would be largely the same here. A Warrior culture with ritualistic hunting practices and honor duels, similar to the Trandoshans but with more of an emphasis on fighting each other rather than hunting down other creatures. Their cuisine stands out because, due to the many poisonous plants native to the jungles of their world, much of it is mildly poisonous to the average person. And don't get me STARTED on their alcohol.
Despite their warrior traditions however, it's actually the females who largely rule them. The men are taught to fight, but the women make sure they SURVIVE. There also happens to be a significant gender disparity, 1 female for 10 males, which makes growing their population difficult even if they were off planet.
I could go on, but you get the gist. Honestly, the races from Mass Effect are some of my favorites.
I'd actually like to add onto and change a lot of my earlier recommendation after further thought in greater depth. I've had time to REALLY expand.
Firstly, something to make the jungle world more unique. It looks like a Kashykk style forest planet from a distance, but a closer look reveals something much more interesting; the planet is surrounded by a massive, planet spanning series of roots, with foliage and other trees growing out from them, all starting from a singular MASSIVE tree roughly the size of Nevada. Does anyone remember that episode of The Last Airbender taking place in the swamp? Where all the trees basically were an extension of the largest tree in the center? Like that but on a planetary scale. The primary tree is also at least semi-sentient, somewhat akin to Eywa from the sci-fi Avatar film.
There is something else of interest about the biosphere; there's basically a constant presence of pollen spores in the atmosphere, apparently created by the primary tree. This stuff acts like a wonder pollen when it makes contact with other plants, causing rapid and explosive growth and fertility. Something that would take months to grow would reach full maturity with a bursting harvest in roughly a week. It also caused truly dead flora to rapidly decompose into compost.
As for the main inhabitants, they are still reptilian. Though rather than Krogan they would be more akin to the Argonians of Elder Scrolls. They are still very warrior inclined.... but VERY much not in the Mandalorian vein. They consider the idea of a fair and upright fight insane and insulting. They favor hit and run tactics, ambushes, stealth, crippling the enemy before they fight and everything else. This is even shown in their honor duels, they DON'T duel somewhere out in the open where everyone sees them, they wait for the bell end basically enter opposite sides of a dense section of foliage and trees, turning it into a vicious combination of hide & seek and first blood gladiatorial combat, with the winner being the one to come back uninjured.
This line of thinking makes much more sense when you find out about the predators on world. Fighting them solo and head on is basically suicidal, with many of them being venomous enough that a glancing hit would be lethal.
And further down below, in the deeper sections of the trees, you find the OTHER dominant life on the world; 40K ORKS!!! The pollen spores from up above come down below the surface, away from sunlight and in a very humid environment, where they gradually clump together to form the Greenskins. Extremely violent, terrifyingly strong and resilient and constantly wandering below, the top dwellers leave them alone to keep the other predators busy. But sometimes one of them is smart and vicious enough to lead an invading force to the treetops above. This is one of the reasons the Gee'Shaw (the Green Scaled, basically their race name) don't really wage war against each other with total intensity, they need everyone available to turn back such a tide.
For cuisine, they are primarily vegetarian by necessity. Meat isn't exactly rare, but something of a luxury, with much of their diet composed of agricultural products. Beyond harvesting foodstuffs in the wild, they also have some agriculture set up. Though, rather than soil like we use, they have large sections of treetops loaded to the brim with mulched and decomposed vegetation serving as basic soil and potent fertilizer. That said, their agricultural methods are basic due to the pollen in the atmosphere DRAMATICALLY cutting down on time needed. They've never really needed to develop their agricultural system in depth.
What really stands out is their alcohol. The most basic is essentially tree sap that has been extracted, exposed to sunlight until solidifying, they ground down into a form of sugar and fermented. This is their SAFEST alcohol, but the hardcore stuff is distilled from the poisonous parts of animals and plants. They naturally have VERY robust and resilient immune systems and filtration systems, making them almost impossible to poison.
They also have Force users, though they are exclusively female for some reason and appear to have a form of albinism. These women are then raised and trained as shamans, the spiritual leaders of their society who wield significant political influence due to their ability to commune with Gee'Aran (Green Mother, their deity and the name for the massive tree that covers the planet).
As for its natural resources.... it basically has its own form of bacta. Large, hollowed out sections of trees and roots where the sap flows and great quantities of spores are introduced to it. The final product feels like slightly thickened water to the touch, looking transparently golden and seeming to shimmer under light. It isn't AS effective as actual bacta, more akin to the Kolto of Manaan, and is very plentiful and naturally self replenishing.
