I think I would agree to lots of this list, but have a few thing I want to expound upon/append.
Regarding your #2: I think resting in 5E doesn't quite work. Short rests could have a place if they were actually short. A full hour is a fairly long time in a dungeon, but very short for a party...
A question for drain magic interactions: it only goes up to second level spells. Can a warlock's pack slots outgrow the rogue?
Regarding that 2nd slot refund: a party member could ritual casts a spell (detect magic, for example). That is a viable candidate for drain magic. You could turn 10...
I didn't think that's their intent. The rule about 1 spell shot per turn being added in 2024, as well as making sure action surge can't be used for multi-casting makes me doubt a monk sub class is the place to allow that.
I have some concerns with 5e's bounced accuracy that I would like to see addressed in a hypothetical 6e: the very flat nature often feels like the difference between an untrained and trained individual is too small, at least at the levels most play occurs.
Other thoughts: I think 5e didn't have...
I have a few ranger spells to offer. They aren't all smite-esq, so let me know if they aren't really what you're interested in.
I like the idea of using ranger spells to reinforce the "expertise " of the ranger, trying to match the spell with skill.

I have had thoughts very similar to this, but have never had the chance to test them out. If you do, please share the results!
As for "compensation", I had thought of a few different paths
Heavy Homebrew: Artificers stop being half casters. Maybe they become the first two-thirds caster, or...
I think we have some different play experiences. Control/buffs from caster are fairly common in my experience. Faerie Fire and Web are staples on my casters (who can have them), as are spells like Bless.
That said, some thoughts in no particular order:
Players focus lots on damage/attacking...
I don't think having to use a feat to get proficiency is an advantage. A similar level sorcerer could be taking some other half feat (Like Resilient: Wisdom), or taking a full ASI.
You seem to be ignoring or otherwise not counting the ritual spells the wizard took. I think they should be counted, they are likely to bring value. Given their fewer spells known, a Sorcerer is unlikely to have those spells, or the value they provided.
I am confused by the math you are doing here, at least in the back half of the quote. The wizard does still know the ritual spells.
Additionally, they are taking the rituals because they think they are better than taking the other options. Are those rituals better than the subclass spells a...
Now that I am thinking about it, are you interested in Bastions? If so
Crafting assorted items
People generally looking for intrigue
Hiring scholars to answer specific questions your characters might have
Warding (spells, lead sheet to prevent scrying, etc)
General "Cosmetic" improvements that...
Looping back here, and I think I've seen it mention elsewhere in the thread.
The revised Star Wars RPG gave players the ability to customize/personalize weapons and armor. I would suggest that those become available to players who craft/have a bastion craft things for them.
Some possible...
Some other items you could add
Bolas: a thrown tripping weapon. Maybe they could have some sort of limited use enchantment? A target wrapped in the bolas is also silenced for example.
Rope in a bottle: When you open this bottle up to 90 feet of rope begins to pour out and harden. The rope...
