Your going to wear chainrings, and they cost a lot! Change those when worn.
I’d just whack a 30t cassette on there and hope that’s enough.
You could use an extender for about £5 and then go up to 34t I reckon.
Also, change your use of the word ratio for range. Range is the spread of gears, ratio refers to the specific sizes.
