The Sorcerer and wizard spell list have always been slightly different in 5e. There is a lot of overlap, but sorcerers tend not to get out of combat utility spells. There are a couple of sorcerer exclusives, such as Chaos Bolt.
Coming from PnP, Blade Ward is generally considered a horrible spell. Minor Illusion is a good as the DM lets you get away with. But I've never found it effective in BG3. Longstrider, Jump, Magic Missile, Mage Hand, Find Familiar are all useful and don't care what your INT/CHA scores are.
If OP wants mobility, that's probably great. Also magic missile for ranged options since 14 dex vs 18 is 10% lower hit chance.
I've personally never found a use for blade ward. When something hits my casters/half casters with blade ward, it's almost always a spell, bomb, arrow, etc. Better to mystystep away or trust nothing /wants/ to particularly kill the high AC dex character
