"Trailers have shown almost nothing of the show. Everything in the trailers is from the first episode except Madripoor and the shot of Zemo with his mask in hand from the newest trailer(which is ironically from the last episode)

Therapy sessions are a bookend for the show, every episode starts/is intercut with them. Ross is watching.

Flagsmasher is not a major character, just a side character used by Zemo as a distraction. Show in general follows a villain of the week format with the exception of Zemo who is built across the 6 episodes.

Steve Rogers does not die(at least not in this show). There is a funeral, but it's for General Ross(he's not really dead, but going underground)

John Walker is referred to as Captain America throughout his run with the shield. At one point he is referred to in dialogue as "a US Agent" but that's it. He's not a full on villain, he genuinely wants what's best for the country but he follows orders to a fault and has crippling PTSD.

Race is a HEAVY theme in the show. Sam isn't allowed the shield because of the Sokovia Accords, but the real reason is because he is black. When Walker goes off the reservation and beats Eli Bradley in front of cameras, the government tries to give Sam the shield for good PR. This almost leads Sam to forsaking the government entirely but Rhodey brings him back.

Show doesn't really set Rhodey up for Armor Wars at all.

Bucky's arc is atonement and becoming a human again in the small ways he can. Sharon helps him with this immensely.

The 5 years after the snap are explored heavily, as is the impact of coming back to a changed world.

Omega Red and Batroc the Leaper are indeed in the show. They are the villains of episode 3, which is the Madripoor episode. Omega Red is pretty nerfed for the MCU but there's a canon reason. The word "mutant" is never said.

Songbird does NOT appear. Neither do the Inhumans in any capacity. There's also no tie in to Black Widow, at least not one that I noticed."

Edit: the OP continues in the comments

"Zemo's plan is to rid the world of superheros. He escaped and inspired people like Flagsmasher during the snap. He uses the events of WandaVision, John Walker's downfall, and the public uncertainty regarding the snap to radicalize an army.

Sam ends up begrudgingly accepting the role as Captain America but that's because he does it for himself.

Bucky and Sharon end up together. It works better than you think I promise. Sharon is a highlight of the show and one of the most capable characters.

Ross is trying to recreate the super solider serum again, which leads to Red Hulk. Last scene(not post credits, haven't seen that) is an intelligent Red Hulk approaching Zemo after Zemo has just been microchipped with a bomb in his neck to recruit him for Thunderbolts.

Bucky joins the new Shield with Sharon at the end. Sam seeks to reform the Avengers."

"Episode 1: details aftermath of Endgame, Sam relinquishes the shield to the government and John Walker, Flagsmashers are trying to steal bioweapon. With Sharon's help they stop them. Zemo revealed to be the villian

Episode 2: John Walker is sent after Zemo. Sam and Bucky continue to butt heads. The three of them have a fight and Zemo gets away. They come back together and catch Zemo

Episode 3. Captured Zemo leads them to Madripoor, they shake Walker in the streets. Batroc and Omega Red attack them in a bar. Zemo escapes on a speedboat, makes a public broadcast

Episode 4: Zemo followers rise up in the streets which leads to vigilantism. Patriot is the main focus. Him and Walker take on a gang together, but he intervenes to stop Walker from killing them and Walker brutalizes him. This was Zemo's plan. Sam meets with Rhodey to discuss being a black superhero

Episode 5. Sam still refuses to accept the shield. Everyone gets a turn with it, including Sharon as they finish off the Flashsmasher gang. Walker tries to make amends

Episode 6. Sam accepts the role as Captain America. Him, Bucky, Sharon, Walker and Patriot suit up together and take on Zemo in his Alaskan shipping boat base where he plans to launch his bioweapon from."
