How can I get more Bonus actions?

Hi everyone!

So I'm playing a Great old one, Warlock, in my current campaign; we're playing Strixhaven!, but one thing that I find SO frustrating is just the lack of bonus actions Warlocks have, and my character is a Satyr, so I don't get any racial bonus actions.

I've taken Hex. I know I could take Spirit Shroud or Far Step, but I am a major planner. I'm currently level 2, and I have a document filled with every spell, eldritch invocation, feat, and ability score improvement I want to take as I level up. I want to really emphasise I'm not just picking the most powerful spells or anything; I'm picking the ones that suit my character; I've just never played a spellcaster before, and I wanted to be able to be prepared as we level up, so I know what I'm doing. I haven't picked any of them because they don't really suit Violet (My character).

So my question is, how could I get more bonus actions? I know I can multiclass, but what would the best multiclass option be? Are there things I can do as a Bonus action I just don't realise? Anything else?

Any Ideas Would slay :)
