Flower seed mix

Inland SEQ Based, in a spot that will get heaps of sun.

I’m wanting to seed a small patch of my yard with flowers and noticed a few bee or butterfly friendly mixes available in larger quantities from various online retailers. Is there any one that has a better value or better success rate? Should I get multiples that suit different seasons? I don’t really mind what grows in this spot, I just want some beneficial insect attracting plants that look pretty for as long in the year as possible. I plan to plant it sort of chaoticly
