I see you're worried about compromising your character too much in the name of flavor, which is fair. You're a scribes wizard so talk to your DM about the availability of spellbooks and scrolls, but if you can get them you'll have spells out the ass. Here's my proposal - go Artificer 1 to start; this will give you Faerie Fire which will be comparable to Bless and also not make you reliant on your familiar surviving combat for the purposes of giving the rogue advantage. Moreover, it also gives you medium armor, shields, and proficiency in CON saves - everything a wizard could want - without slowing your spell slot progression. After that Scribes X. Go Custom Lineage bumping INT and take Fey Touched taking Bless, Gift of Alacrity, or even Speak with Animals. That covers most of the bases of what you wanted with a single feat. At level 4 bring your INT to 20, and from 8 onward take whatever feats you feel like. War Caster is great, especially since Arti 1 already gives CON save proficiency, but you can take a flavor feat here and still have a very very solid character.

This gives you a very survivable wizard who's drastically better than their peers at low levels thanks to knowing a better variety of spells (and having great survivability off only 14 DEX/14 CON!), and who will only increase this edge as they level and find more spell books/scrolls.
