Beginner advice

I’m a beginner planning my first outdoor container grow for autoflowering plants in a mediterranean climate and I’m trying to keep things simple without overcomplicating it. I’m thinking of using a quality base soil then adding perlite and maybe coco coir? (I’ve heard 70/30 mixes mentioned) Also, Alga Grow and Alga Bloom liquid fertilizer. Maybe I’ll add mychorrizae fungi as well. I’ll be growing in fabric pots. I just want to know if these things are sufficient enough for a good yield. Should I add some kind of compost? Is there anything essential I’m missing or any advice you can give?? I’d really appreciate advice. Thanks!
