Mostly going off the fan wiki and interviews - still debating whether (and if so, when) to fit in things like the Deadpool movie.
If it's running more or less parallel (this primarily applies to Netflix series) I tend to fit it in before the corresponding Agents of S.H.I.E.L.D. episodes, not least because I generally prefer the Netflix output to AoS.

As for Loki, it does split off into an alternative timeline post Avengers, but I'm adding it just after Endgame (for now) to account for possible timey-wimey shenanigans.
