I should add that kingsnakes, milksnakes, and other, more common colubrids are all good. The common ones are usually common because of ease of care and ease of captive breeding, plus knowledge of the species will be readily available.

I am partial to corns (in colubrids), myself. I find them to be a little less aggressive when wanting food.

Figment will destroy a F/T mouse, don't get me wrong. However, he has never bit expecting food/hoping for food. Same with all the corns I have had over the years (3). I know kings can be very aggressive when wanting food! However, I am sure it varies from animal to animal.

My BCI has a killer feeding response as well, and in general it's a good thing, but especially if you are new to snakes, I think a corn gives the best value. Price, morphs, ease of care, handling ability, will eat anything, etc. They check all the boxes.

Good luck and keep us in the loop.
