Optimize my Swashbuckler/Sorcerer spells known

[odigity]

Started as Swashbuckler 2, currently at Swashbuckler 3 / Sorcerer 1. (Draconic Bloodline, Red) So far I've grabbed:

(C) Booming Blade
(C) Green-Flame Blade
(C) Mage Hand
(C) Minor Illusion
(1) Absorb Elements
(1) Shield

I intend to choose spells to complement my Swashbuckler-ness, even if they're not the best spells in the whole spell list. (No Fireball, because it's outside the role.)

If I somehow make it to lvl 20, I plan to intend up as a Swashbuckler 12 / Sorcerer 8, which means knowing 5 cantrips and 9 spells.

Here are my current top picks, with spell level and key attributes:

(C) Booming Blade
(C) Green-Flame Blade
(C) Lightning Lure
(C) Mage Hand
(C) Minor Illusion
(1) Absorb Elements (reaction)
(1) Shield (reaction)
(2) Earthbind (action, concentration)
(2) Mirror Image (action)
(2) Misty Step (bonus)
(2) Shadow Blade (bonus, concentration)
(3) Haste (action, concentration)
(3) Hypnotic Pattern (action, concentration)
(4) Greater Invisibility (action, concentration)

And here are the seven runners-up that I also considered:

(1) Disguise Self (action)
(1) Feather Fall (reaction)
(1) Fog Cloud (action, concentration)
(2) Alter Self (action, concentration)
(2) Dragon’s Breath (bonus, concentration)
(3) Counterspell (reaction)
(4) Polymorph (action, concentration)

Some other solid choices

(1) Mage Armor a true swashbuckler doesn't wear armor, plus this gives you 13+Dex AC instead of the studded leather 12+Dex
(1) Charm Person a swashbuckler is charming
(2) Blur You move so quickly no one can actually see you, plus with your Dex it would be a good spell
(2) Invisibility Sometimes you need to get away from the adoring fans

I think I would try to squeeze in Invisible and Counterspell.

I like the idea of a Swashbuckler/Sorcerer combo.

Your AC should be 13+Dex anyway from being Draconic Sorcerer.

What feats were you thinking? Warcaster and Sentinel would be a must IMO so you could pull off Booming Blade and Sneak Attack with your reaction all the time.
