Which class gives most new magical powers for 1 level dip

Background: I have a bard, who is a bit lacking in low level spell selection, so I’ve been looking into multiclassing to get some more.

Stats (you can give +2 ASI for the benefit of multiclassing):

STR 11, DEX 17, CON 14, INT 9, WIS 14, CHA 20

So, Wizard is out.

For classes that pick subclass at level 1, subclass features count of course.

From what I have gathered from unofficial internet snippets, Tasha’s Cauldron of Everything seems give some nice options (like 4 cantrips and 5 1st level spells?!). But I don’t have that book myself to verify, and I may have missed other options, so the question:

What is the most different spells or spell-like powers a 1-level multiclass dip can give?

To clarify: I mean spells the character can actually have available, not the number they can choose from. I also realize now, that divine casters who pick spells every morning are their own category, not directly comparable. Still, for purposes of this Q, count the daily prepared spells.

Bard isn’t option for me, so I’ll include it as an example: 4 cantrips, 2 spells, 1 magical ability (Bardic Inspiration).

UA is ok, though I’d prefer official classes.
