I agree with everything except alignment. Alignment is something that 5e has distanced itself from except in rare circumstances. I think the idea is to get away from "I would do this because I'm lawful good" and instead "I would do this because my character believes xyz." It's a subtle difference, but character motivation is more important than the box the alignment system puts you in. Just my opinion of course.
Equipment customization is pretty important at character creation though. Larian should do 1 of 2 things.
1. Allow us to customize starting equipment as in traditional 5e rules.
2. Start with no equipment and find scattered weapons and armor in the first room of the mind flayer ship. BG2 did something similar. You were a prisoner that broke free and found a room with various weapon and armor that you could dawn to your liking.
I wasn't aware the alignment was an issue, it's still present in the Player's Handbook and plays a role in races and spells, maybe I missed something. In any case, it's not a very important feature to me so I don't want to make a fuss of it (or to revive a debate).
I'm all for solution 2 or any way to integrate that in a story, at the beginning or very early in the campaign. It's the perfect excuse to make that more realistic. Some games even put the character creation in that form (Morrowind, PoE 2 for instance), perhaps it's pushing it a bit too far, especially if the user customizes the looks. But for the initial equipment it would be great.
Tbh, I think Pathfinder Kingmaker does the best job of alignment - your actions can cause it to change over time.
Yes, they did well for that, and many other features! Sometimes I found myself looking for the desired alignment in the dialog options, though, or reluctant to select an option that I would otherwise have found appropriate, just because it didn't match the character's alignment. Perhaps I'm a bad roleplayer

Or more likely, it's natural to go outside those boundaries now and then.
