Since Marvel Studios sometimes releases prequels, one shots, and credit sequences, it can be hard to tell exactly what is the best way to watch the MCU. Here's my two cents.
Since there are different ways to determine what order to watch these stories in, there are often disagreements about what is the correct order. Some people only talk about the movies in broad sweeping statements, some people are willing to cut between scenes in different movies. I am somewhere in between.
I try to keep movies intact as possible. There is a reason that they're structured the way that they are, and that's because it's the best way to see the story unfold. However, every now and again some stories are told in parallel or there is a time jump, either forward or back.
I don't count the time jumping of Endgame or Loki to be set in the era the characters are acting in but rather how they fit into the characters' journey. I find it a little silly to have one of the first things that the viewer watch is Loki and Moebius arriving in Pompei to test their theory, for example.
I do think that some flashback stories stand on their own, for instance the openings of Thor or Black Panther. However, I don't count the Collector telling the story of the Infinity Stones and the Celestials as I think the point of that scene is less about what happened in the past than it is about the characters understanding what had happened. For the same reason, I don't have the flashback story that Erskine tells about Johann Scmidtt being separate in First Avenger.
I did include Agent Carter but not Agents of SHIELD, mainly because Carter is more bite-sized and can be folded into a rewatch rather than the larger Agents of SHIELD. Also, AOS is harder to pin down on where it fits in. I'm also not including other non-Disney+ shows, like the Netflix shows, Cloak & Dagger, Runaways, or MODOK.
But, now that we've set up the rules, let's roll up our sleeves and dive in.

I put years in here, but they should be taken more as a guideline. Sometimes they're spelled out and sometimes they're not. And even if they are spelled out, sometimes they don't quite line up or straight up contradict each other.
