What do you recommend for African/Mixed DNA tests?

Hi everyone! I'm since a few months looking into getting a DNA kit, but the reviews and info online are making me have many doubts about which one to get.
I'm more or less aware of my ancestry but I've no records or anyone else I could ask at this point. My family is from Cape Verde, so a very small place, quite similar to Caribbean islands in terms on genealogy, only that afaik there was no population there when the portuguese first arrived. My mom always told me one of her great-great-great grand parents was from India (she's not 100% sure tho) and, from my dad's side, there are portuguese somewhere in the tree. But I'm just very curious about my roots hence why I'm looking for any tips on which of these online kits have a wider DNA bank. Thanks in advance!
