That’s pretty solid, here’s what I would tweak:

Phases 1-3 (stays the same)

Phase 4 - Aftermath

Far From Home
Falcon and Winter Soldier (these first 2 show a bit about the blip and the legacy of our 2 main heroes in the infinity saga)
Daredevil S1 (introduces kingpin/Matt)
Hawkeye (christmas!!!)
GOTG Holiday Special (christmas!!!)
Wakanda Forever
GOTG Vol. 3
Loki (ends on something relevant to the saga and is a prelude to the multiverse phases)

Phase 5 - Spiderverse (this one is my fav)

Into the Spiderverse (introduces the multiverse in terms of Spider-Man really well)
Spider-Man 1-3
TASM 1-2
Venom
No Way Home

Phase 6 - Multiversal Mutants

(This one is the same)

Phase 7 - Multiversal Collisions

AMATW: Quantumania
Loki S2
Deadpool
Logan
Shang Chi
ATSV
BTSV
Deadpool 3

This order keeps focus on the main MCU and allows for the best of the other universes, and skips the really bad stuff (Thor 4 👺) and the currently irrelevant stuff (moon knight, eternals, etc.) Phase 7 will probably change as new stuff is released and the multiverse threads continue.

EDIT: If I remember correctly Kingpin ends up in prison at the end of Daredevil so it may not make sense there. Ideally it would go in phase 3 but that would disturb the rule of 8s. You could take it out and move Shang chi up if it bothers you.
