All this and the ability to change memorized spells at will.
These changes should come when the Sorcerer class is added to the game at the latest. Otherwise what's the point of a Sorcerer to begin with if Wizards can learn even Cleric spells and can switch their memorized spells at will.
Scrolls being free for all isn't good for the game either. It makes magic feel mundane and spellcasters far less special or needed. You should have at least SOME understanding of magic through multiclassing or a feat to unlock scroll use.
Magic in BG3 ties directly into the resting system as well. It does trouble me that Larian have made zero comments about magic system or resting. I can't help thinking they want to change all of it towards a classless/DOS system because they think less restrictions automatically mean more fun.
