So, it seems that WoTC design philosophy is very much going in the direction of letting players do whatever they want in creation of their characters. Imagine a character, we’re writing the rules so you can implement that dream w/o obstacles. And while I’m not opposed to this I wonder if allowing maximum freedom in character creation ultimately kneecaps creativity in play.

WotC design philosophy is going in the direction of giving players more and more choice in what characters are supported
as long as they are of the appropriate level.
Tasha's and 2020 definitely opened the fighter up massively. I'm only slightly exaggerating when I say that all pre-Tasha's classes except the pseudo-multiclass Eldritch Knight had to be mundane guys with weapons and armour who Just Hit Things and were little more use out of combat than a commoner. But only slightly exaggerating. Tasha's and Wildemount
definitely expanded the fighter out of "just hit it" territory by adding the Echo Knight, the Rune Knight, the Psi Warrior, and letting the Battlemaster use their maneuvers for appropriate skills. So yes there is a massive range of liminally magic characters (especially as fighters and rogues) that are now possible - but that's not Maximum Freedom. Just more freedom within appropriate level derived limits.
Like, at some extreme ends, if on the one hand you are a spellcaster with your pick of any spell you want at any time vs you are a arcane conjurer with only access to arcane spells in the conjuration school?
Ironically this is a type of freedom that seems to be less and less at the forefront as 5e has gone on. At launch in 5e there was an entire class (and a historical one at that) dedicated to choosing almost any spell from a ridiculous list so they always have an optimal choice - the wizard. There was one class option that did something similar; the warlock's Book of Ancient Secrets invocation for Pact of the Tome. There was of course also the Lore Bard
Since the launch of 5e there has been precisely
one subclass that has expanded on this - the Order of Scribes. It doesn't seem to be something that WotC has expanded on (unless you count the Cleric, Paladin, and Druid lists expanding).
What has happened is that the two classes with a cripplingly low number of spells known, the Sorcerer and Ranger now get to know more spells than a wizard or paladin respectively can prepare at one time. But this is fixing what was basically crippled rather than opening the floodgates.
I feel like in play, the all spells guy will have whatever is optimal at any time and has the opportunity to maybe be creative in choice, but will mostly just keep dropping whatever is the most fitting Big Hammer. On the other hand, the strict conjurer being so limited, will get creative in the use and implementation of their spells, test the boundaries of them.
And the "All spells" guy doesn't exist in 5e. What's actually needed for creativity is some sort of balance; the "strict conjurer" if they then need to dump spells into offensive and protection magic end up in a situation where the only tool you have is a hammer.
To put it into actual context every single ranger I've seen in play has by sixth level known (a) Hunter's Mark for their combat damage, (b) Goodberry or Cure Wounds for party healing, and (c) Pass Without Trace for stealth. All are great choices but they all kinda do one thing well and aren't good for creativity. At sixth level a ranger knows a grand total of
four spells - and with these three locked in that's basically one spell to be creative with because keeping people alive and doing damage take priority. And with one spell when the only tool you have is a hammer...
Or rather it wasn't. As of Tasha's Cauldron of Everything a (non-Hunter, non-Beastmaster) will also have Speak with Beasts, Beast Sense, and two spells from their subclass. This is hardly "all the spells" - but is enough for creativity.
Or in short I reject the premise of this. The only place I see any sort of "maximum freedom" is in races.
