I've been in Isolation with COVID and just rewatched the entire MCU (ones available on Disney+ anyway) in timeline order. The only real reason for watching timeline order is seeing a better story arch for Fury. Phase 3 movies were generally far better than phase 1 and phase 2.
Actually I’m glad you brought this up because started watching Iron Man 1 the other day and realized that it makes more sense now to watch the movies in chronological order. Is this the order you watched them:
"Captain America: The First Avenger"
"Captain Marvel"
"Iron Man"
"Iron Man 2"
"The Incredible Hulk"
"Thor"
"The Avengers"
"Iron Man 3"
"Thor: The Dark World"
"Captain America: The Winter Soldier"
"Guardians of the Galaxy"
"Guardians of the Galaxy Vol. 2"
"Avengers: Age of Ultron"
"Ant-Man"
"Captain America: Civil War"
—This will be when Black Widow takes place——
"Black Panther"
"Spider-Man: Homecoming"
"Doctor Strange"
"Ant-Man and the Wasp"*
"Thor: Ragnarok"
"Avengers: Infinity War"
"Ant-Man and the Wasp" mid-credits scene
"Avengers: Endgame"
"Spider-Man: Far From Home"
Whether you want to catch up on all of the Marvel movies in chronological or release order, here's a handy guide to binge the MCU.
