I don't deep fry very often, the fryer is cumbersome to take out from the bottom cupboard, one has to change the oil every few uses, and even then, no matter how tasty the product, there is a bit of a fast food odour that lingers for a bit after.
Still, homemade french fries, with lemon-thyme aioli is an every three months pleasure not to be missed; some good veggie tempura about as often. Once a year only, I will make mini-doughnuts. I can't be bothered unless I make a dozen, and one must then generously gift the neighbours or face un-due weight gain!

No hood as such, I can make use of the vent beside the oven; but it is necessary to give the closest upper cupboards a wipe after.
