Winter woodenware project list — scraping, scorching and painting 30 boxes over the dark months, what order?

Texas, fourth year, grown from two hives to fourteen and the pile of spare and retired woodenware in my garage has grown with it. Boxes with propolis an inch thick in the rabbets, frames with blown-out comb, three floors with rotten corners, and a stack of supers I bought secondhand and have never properly cleaned. My draft plan: sort everything into keep, repair and burn first. Then scrape all the keepers down to bare wood in the rabbets and top edges — I've learned that a hive tool and a warm afternoon beats any clever gadget. Then scorch the insides of the brood boxes with a blowtorch, mostly for hygiene and partly because it makes me feel better about the secondhand ones. Then repair, then paint outsides only, two coats of exterior latex. Questions for the people who do this at scale. Is scorching worth it on boxes with no disease history, or is soap and water enough? Does anyone dip in wax rather than paint, and is that realistic for a hobbyist? And how do you treat secondhand gear of unknown history — is there a point where you just don't buy it?
